Hello!
My name's Sara and I created Starfish Maths to bring A level Maths teaching in bitesize videos by topic. I wanted to make Maths personable, engaging and as clear as possible. I use plenty of examples and exam style questions for you to try - always watch with pen and paper and have a go yourself. I speed up the working in places to encourage you pause and play, working at your own pace.
Whether these videos serve as an introduction, general practice or revision, I hope they are helpful to you.
Keep practicing and enjoy!

A Level Maths exam question on functions - differentiation and graph transformations
Переглядів 5 тис.2 роки тому
This A level exam question explores the graph of a function, and involves differentiation with exponentials, the product rule, finding stationary points, graph transformations, and the range of functions. Lots of skills to practice! Enjoy! www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com
A Level Maths exam question on circles
Переглядів 3,6 тис.2 роки тому
Today's exam question is on circles. The first part is pretty standard, the second part a bit more creative. Enjoy! www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com
A Level Maths exam question on factor theorem, algebraic long division and integration
Переглядів 2,3 тис.2 роки тому
Today's exam question is from an AS paper, all about a polynomial. We use the factor theorem, long division (and I have a new method for that today) and integration to find the area under the curve. Enjoy! www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com
A Level Mechanics - Forces on a slope and friction
Переглядів 1,7 тис.2 роки тому
This video is an introduction to managing and resolving forces on a slope. I show you how to label forces, break them into components, write equations and solve them. We use a block at rest on a rough inclined surface. Enjoy! www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com
A Level Maths exam question on trigonometry multiple angles
Переглядів 1,3 тис.2 роки тому
Hello! Today we have an A level question about trigonometry, using some identities and multiple angles. Hope it's useful to you! www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com
A Level Maths exam question on integration by substitution
Переглядів 4,5 тис.2 роки тому
This is the first video of a more juicy exam question, shot very simply off my screen. A bit different to my usual teaching videos - let me know what you think in the comments! Is it helpful? Do you want more and if so are there any questions you would like me to look at? www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com
A Level Mechanics - Newton's second law, mass and weight
Переглядів 2,3 тис.3 роки тому
This video practices using Newton's second law of kinematics, f=ma. A specific example of this distinguishes between mass and weight. Three examples are used, the last of which is on a slope. Enjoy! www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com
A Level Mechanics - Resolving vectors on force diagrams
Переглядів 2,5 тис.3 роки тому
This video begins to explore basic force diagrams and resolving vectors. It assumes some knowledge of vectors, which is covered in a previous video. Questions involve finding resultant forces, and using equilibrium. Enjoy! www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com
A Level Mechanics - Vectors
Переглядів 6 тис.3 роки тому
This video covers the basics of vectors for A Level Maths - starting with how to draw and write them, add them, find the magnitude and direction, find vectors between coordinates, position vectors, and vectors in 3 dimensions. Hope you find something useful! Enjoy www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com
Binomial approximations
Переглядів 18 тис.3 роки тому
Following on from simple binomial expansions, this video considers when the power is not a positive integer, and a binomial expansion can be used to give an infinite series for approximation. I cover 3 examples, all exam style. Enjoy! www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com
Proof by contradiction
Переглядів 12 тис.3 роки тому
The second of 2 videos on proof - here we have proof by contradiction. This is a very powerful technique which involves proving that the opposite of a statement can't be true. I cover 5 examples, each full of tips and tricks which you may use again in similar problems. Enjoy! www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com
Proof - counter examples, proof by exhaustion and direct proof
Переглядів 3,8 тис.3 роки тому
This is the first video on proof for A Level Maths, covering disproof by counter example, proof by exhaustion and direct proof by deduction. I use a few examples of each, including expressions for odd/even numbers, consecutive integers and rational/irrational numbers. Enjoy! www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com
Sin and cos rules
Переглядів 2,5 тис.3 роки тому
This video covers the sin and cos rules for triangles, as well as the formula for the area of a triangle. 3 exam style questions included. Enjoy! www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com
Geometric series
Переглядів 2,2 тис.3 роки тому
This video covers geometric progressions, sequences and series. We derive formulae for the general term, the sum of the series and the sum to infinity of convergent series. 3 exam style questions covered. Enjoy! www.buymeacoffee.com/starfishmaths www.starfishmaths.com starfishmaths@gmail.com

The Product and Quotient Rules for Differentiation
Amazing video. You explained it so well. Thank you so much ❤
Very helpful
Superb explaination keep it up medam
Thank you very much 😊
Please, aid me to have all the examples solved.Thank you.
Please, how can l get all the perfect examples being solved as a guide. Or notes to rely (depend) on?
Thank you so very much for doing all of this explanation, you made my life in mathematics easier with CAST diagrams💯
Damn who ever created those formulas is a made man...
Can I have your number ma'am
hey, im new to london als and i wanna know if this is the same syllabus as in core mathematics. anyone? thx
Nice explanation also beautiful 😍 mam
excellent question. thanks
5:30 the last one you did was wrong, my answer came in different, then I rechecked it with a Math app named sizzle and it was same as my answer, means your answer is wrong for the 6th problem
thank you
Your are soo good Thank you very much❤
thank you so much for these videos
I am from india ❤
lord cry
You can also use implicit differentiation for the gradient of l, which is quicker for me.
I came here to get more teaching ideas and i did. 🇵🇰
Mam You are a great teacher.
Mam you are a wonderful teacher. Watching from Pakistan 🇵🇰
Very well explained mam. Watching from Pakistan 🇵🇰
Just didn't understand the thing with negative range -180 < x < 180
11:10 why only A even C will be positive right!!??
good
As a beginner this didn't help me much 😔
BRO THIS IS THE MIST BASIC THING PRACTICE IT NOW!!!!
It's very helpful to me. Thank you very much for your help and God bless you.🥰🥰
Thank you, it was a great video on differentiation. It really helped me out a lot.
Please who can help with linear function rule videofor differentiation 🙏🙏🙏
I don't understand for the 3/2, doesn't exactly followed the chain rule, I'm confused 😵💫
Hey maam in 10:58 i am bit confused on you got the answer second derivative is equal to 2a?
how did the fraction change from -1/2 to -3/2 5:51
im failing maths aren't i
How many of you’ll clicked into organic chemistry tutor and came back to this video cause it was too advanced
me
😅✋️
Dude 😢 how did you know
It actually feels easy now that you explained them in a nice way. Thank you so muchhh✌️🥺
❤❤❤❤❤❤❤❤❤❤
I want to know how to use differentiation in word problems
I want to do that of logarithm
I want to do that of logarithm
i thought i was going to fail my test until i watched this
Much thanks
You teach well
Wow she a great teacher
❤
Thankyou so muchh
