Question

prove cos² theat + sin²theta = 1​

Answer 1

Answer:

Hey mate, ✌✌

we know that,

sin theta = P/H and cos theta = B/H

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

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

P^2 + B^2/ H^2

From pythagoras theorms H^2 = P^2 + B^2

H^2 / H^2 = 1

So, sin^2 theta + cos^2 theta = 1

Hence, proved.

Hope it helps you..
