Any alternative methods for Q9 (c)?
Need to redo the math again, it just came in my thoughts while solving the QP.
Do you still watch my videos? I am quite surprised
so underrated loved it
SIR THERE IS MISTAKE BUT ANSWER MILSE SOME HOW 0.5 SQUARED IS 0.25 YOU WROTE 1.25 58:47
Due to dixlexia, sometimes I say something and write something else, and vice versa, but if the students can understand, that's served the purpose. But thanks for your honest comment.
Abiyaz er sir😮
This is peak.
Sir in b part, how do we know it is a right angled triangle, like it didn’t mention
Sinx = P is a good enough definition to draw a right angle triangle and use the ratio of length p over 1
Thank you sir I really apriciate your video
in question 8b, after substituting x=0 in the equation of the curve, it would be y=2 30:06
Sir, there is a mistake in Q 23(b) 1:11:20 • The triangle C can be drawn by multiplying the matrix (P) with the coordinates of triangle A and plotting them in the graph and joining them.
😊
Assalamualaikum sir. Sir you should make more videos on refractor lab book solutions.Btw sir this was very helpful
sir apni kothai poran?i want to join
Keep the channel subscribed, l always post the solved question papers with my students. You can get those solutions even without being my student. It's a great pleasure that these solutions are helping 🙏 you.
at 1:29:07 it will be -3 rather then -c, the dictation was correct but the written value was wrong
thank you sir
@ 32:43 it would be 61.1
Sir kamun asen?
Question 1: 0:27 Question 2: 2:43 Question 3: 5:38 Question 4: 12:18 Question 5: 17:30 Question 6: 26:23 Question 7: 29:45 Question 8: 38:12 Question 9: 46:53 Question 10: 59:46 Question 11: 1:10:03
Thanks a lot Avner
29:24 it will be y=2x+1 instead of y=3x+1
@ 23:06 a) will be clockwise
at 13:48, the final answer will be 33.04 instead of 30.04
Thank you sir,you are a hero
yes sir understood
Sir it would be helpful if you upload some add maths paper 2 video. Thank you.
Sir please upload more paper 1 videos as we have exam on 16th
Ok, noted I will inshallah
