Question

if cos theta equals to sin theta the value of 2 sin square theta is​

Answer 1

Answer:

2sin²theta=2(cos²theta-1) ....(as sin²theta +cos²theta=1)

=2cos²theta-2

Answer 2

Answer:

Step-by-step explanation:

Given that,

cos theta = sin theta

Theta = 45°

co 45° = sin 45° = 1 / √2

∴ 2 sinsquare theta = 2 × ( 1/√2 )whole square = 2× 1/ 2= 2/2 = 1 is the answer

( ∵ square and root are cancelled, we get 1/2)
