Ma'am in 1:03:52,
Can we also solve the equation like this -
sin - cos = 0
(sin - cos)² = 0
sin² + cos² - 2sin.cos = 0
sin. cos = 1/2
Now,
(sin²)² + (cos²)²
Or,
(sin² + cos²) - 2sin²cos²
1 - 2sin²cos²
1 - 2( 1/2)²
1- 1/2
= 1/2

[@smritisingh7653]

Mam you should explain a bit more logically, like you are teaching an average student also. It seems to look like, that you are teaching a topper who knows the advanced and basic things as you know. So kindly explain every part clearly as possible with logic.
Thank you
