Question

prove that cos^2 theta + sin^2 theta =1 ​

Answer 1

Hello cutie pie❤️___

Cos^2 theta + Sin^2 theta = 1.

We know that :

H^2 = P^2 + B^2 ( Pythagoreans theorem)

Divide H^2 On both side

H^2/ H^2 = P^2 + B^2 / H^2

1 = P^2/ H + B^2/H

1 = (P/H)^2 + ( B/H)^2

1 = SIN^2 THETA + COS^2THETA

HENCE PROVED

HOPE IT HELPS DEAR❤️
