Question

is cos square theta + sin square theta equals to 1​

Answer 1

Answer:

yes cos square theta + sin square theta equals to 1​

Step-by-step explanation:

sin theta = p/h

cos theta = b/h

so, sin²theta + cos² theta = 1

then,

( p/h)² +(b/ h)²

p²/h² + b²/h²

p²+b²/h²

p²+b² = h². ( by Pythagoras theoram)

h²/h²= 1

hence proved

Answer 2

Answer:

it is the formula of tenth class

yes sin^2 theta+cos^2theta=1
