I haven’t understand As. no.6 of ex. 7b

Darshan says

Bro it’s very easy

Lhs is question and 3 is taken common

Vedendra says

Take the value of x and put it in the rhs then cut a fron denon ane nenom the by exponent rule you can cut 3×2/3 = 2 while cuttin both the 3rs and leavin 2 behind …therefore sin2¤ +cos2¤ =1 …hence proved
