Question

if Sin² thita - Cos² thita = 0 so how much value of thita?​

Answer 1

Answer:

sin² theta-cos²theta

=1 theta=1

theta =90°

Step-by-step explanation:

may be this could be the answer...

Answer 2

Answer:

Step-by-step explanation:

Sin²(θ) - Cos²(θ) = 0

i.e., Sin²(θ) = Cos²(θ)

Sin²(θ) = 1 - Sin²(θ)

2 Sin²(θ) = 1

Sin (θ) = ± (1/√2)

     θ can be nπ ± π/4 , n=0,1,2,3,...,,,
