thank you sir after seeing this question I know that it get solved by whole squaring but I get stuck in conversation of sin in cos@ thank you

[pxg_]

This the easiest solution of this question here....love this💖💖💖

[sathyamn]

The concepts are explained crystal clearly. Thanks for the Maths lessons.

[rupamsengupta]

sir if we go on doing the trigonometric identities but the process is in right way and if we can't prove the solution then in this case step markings will be given?

[ExamGuru-vzex]

Sir you are brilliant and best teacher

[sumbulkh]

Hello sir!!! I have a doubt can't we cancel d 1 we get on both sides and then we will get -cos2 theta but then we can transpose all that to d other side leaving 4 behind and then using d identity a-b whole square!???? Sir can I do it or in this way, I still do get d right answer???

[kinnavbharali]

Sir I have a this video you wrote -4 at RHS at the bottom left of the board then how it became +4 at the top right?

[kartikeypatel]
