Question

if sin theta is equal to 3 by 5 and Cos theta is equal to 4 by 5 find the value of sin square theta + cos square theta​

Answer 1

Answer: Hii! Genius

This is your answer

As we know that sin²theta+cos²theta =1

By identity we know

Prove

Step-by-step explanation:

Given,

Sin theta =3/5

Cos theta=4/5

Putting the value in sin2theta+cos²theta

(3/5)²+(4/5)²

Solving that

9/25+16/25=1

Hence get the value of sin2theta+cos²theta
