Question

If sin 0-cos0 =0 then what is the value of (sin^4 0 + cos^4 0)?​

Answer 1

Answer:

is 2cos⁴0 or 2sin⁴0

Step-by-step explanation:

assuming 0 is not zero its theta

then from first eq.

sinθ-cosθ=0

sinθ=cosθ

sin²θ=cos²θ

the sub the values in eq. 2

sin⁴θ +cos⁴θ = (sin²θ)²+(cos²θ)²

=2cos⁴θ or 2sin⁴θ
