Equations of Tangents to Circles (Complete Grade 9 Lesson) | Grade 9 Playlist | GCSE Maths Tutor

I think there is a mistake in the last question where line crosses the x axis the coordinates are (22,0). i also checked in desmos but can you please check it again and help me. it would be really helpful. thanks

this topic was always that 1 topic i wouldnt ever revising for as i never understood it. but after a while of watching unhelpful yt vids about this topic i came across your video and i can proudly say that i understand this topic fully!!. thank you so much sir, you dont know how much of a help you are to gcse students

But how about for questions for which the origin isn't (0,0)?

song name?

is this included in OCR 21st century higher

How many marks are these questions

If you used decimals other than fractions would you still get the marks? E.G at timestamp(37.58) you put 16 2/3 but i got 16.6 in decimals. would it still count?

thanks for all ur help btw!

how to find the gradient of the line AO

HHHHHmjHHHHH

ive never understood this topic, thank you so much i feel so much more confident with these questions now :) 🙏

is it likely to see a question like the last one on an actual exam?

is this calc or non calc?

explained it really well, thank you!

Got a 57/80 on a higher paper in class today,had some real fuckups to get that low score,but this grade 9 question was the only one I didn’t understand,turns out those 5 marks are fucking simple and I just hadn’t learnt it

why don't u minimize the GCSE MATHS TUTOR banner on top by a bit to have a slight bigger space to work with

Doing my first maths GCSE in one hour- thank you sooooo much for all the work you do- I feel so ready!!!

how do u know o is the centre on triangle oab

i literally love you so much you and freesciencelessons should get a knighthood for being education legends

how many marks would this be in the exam?

Why these always gotta be so long man

towards the end when you was finding c you did (7/2 root 7) + (9/2 root 7)= 16/2 root 7. I thought it was 16/4 root 7

For the last question, I rationalised the denominators which also led the answer to look a lot neater. Would it still be accepted? Also I just came across your channel preparing for next set of mocks and I have to say it looks really useful and I will use it many more times before the summer exams.

Thank you

Wow keep it up!

Instead of finding the perpendicular bisector gradient (tangent) to the radius by circle theorems, you can also use implicit differentiation to find the gradient/normal or parametric differentiation when the gradient function is set to -cotθ and plug θ value to find the gradient/normal. After that you plug in the coordinates into the straight line formula y-y1=m(x-x1) to find the equation of the tangent/normal.

Hi sir does one think that gsce will go ahead

are these new videos or re-uploads

first
