Question

(sin theta + cos theta )²- (sintheta )²= 2 sin2 theta​

Answer 1

Step-by-step explanation:

$\sf{sorry question might be wrong }$

Answer 2

Answer:

Yes, sin²Ф = (sinФ)²

Step-by-step explanation:

We have to say if

sin²Ф = (sinФ)²

For writing the trigonometric expressions in exponent form, we take exponent on the trigonometric functions instead of exponent on the functions and angle.

For example, tan³Ф, sec²Ф, e.t.c.

Therefore, the given statement sin²Ф = (sinФ)² is True.
