DUDE thank you so much. Your explanations are so clear and in depth, you always go over everything you're doing which is so helpful. God bless you good sir.
My CIE exam is tomorrow, I just wanted to thank you for the wonderful teaching and worksheets you provided. Also there is a mistake in your working in the section : (Mixture of All Questions) Question 2 part (ii) the y coordinates are wrong it should be 9/2 and 7
Now there are questions regarding the equation of circle in coordinate geometry and it would be great if u revised the coordinate geometry with equation of a circle
It was really helpful .. don’t you post your worksheet !? Bcz sometimes its hard to go through it on a video if u can post it then it’s gunna help evryone .. and thanks for your videos it’s really helpfull
Hello there. Exam hack videos tackle common exam questions. I haven't ever seen them ask a question on just quadratics so it would be hard for me to do a video on them. What is it about quadratics you are struggling with?
Hi i have a question, from the worksheet on coordinate geometry mixed questions, Q2. Why did you multiply the equation of the prep. Bisector by -1. You wouldve gotten coordintes of C and D regardless.
Also please try to reply as soon as possible. I know its a little difficult and i fully thank you for helping but i have to give my CIE in 12 days so please and thankyou.
I don't. But even if I did multiply an entire equation by negative one it changes nothing in terms of the equations validity other than possibly making it look mathematically 'cleaner'. Look which do you prefer: 1. -y = -x + 3 2. y = x - 3 Both equations are exactly the same. But I multiplied both sides of equation 1 by negative one to get equation 2. I would prefer to use 'y = x - 3' to make other calculations as it's in a nicer form. It has less negatives, you also have positive variables so I'd bet you'd be less likely to make mistakes in using the 2nd equation. In Q2 on the Worksheet: I simply go from something like this y = -x + 13 to this y = 13 - x I just switch the -x and +13 around because for me it's cleaner/easier to deal with. But of course you don't have to both forms are equivalent. But I would have some mathematical manners and keep your work looking clean. ;)
Thankyouuu so much really appreciate your help. Your actually helping so many students specially now more than ever due to the covid situation. Lots of gratitude from Pakistan 🇵🇰
Sorry just one thing looking at the question I cannot understand how it can be a positive gradient on 12:19 it would be very helpfull if u could explain this cause I cannot see how the midpoint of (6,5) can pass through the x axis if it is considered to have a positive gradient
