Prove The Identity, 1.) Sin Theta = Sin\Xb3 Theta + Cos\Xb2 Theta Sin Theta

Prove the identity

1.) Sin theta = sin³ theta + cos² theta sin theta

Step-by-step explanation:

to prove this, use trigonometric identities and factor out the best possible it can be

sin theta = sin³ theta + cos² theta sin theta

factor out sin theta in the right side of the equation

sin theta = sin theta ( sin² theta + cos² theta)

from trigonometric identities:

sin² theta + cos² theta = 1

sin theta = sin theta (1)

sin theta = sin theta
