Question

If sin∅-cos∅=0 then sin⁴∅+cos⁴∅=

Answer 1

Hey there !!!!!!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

sinθ-cosθ = 0

sinθ= cosθ

sinθ/cosθ = 1

tanθ = 1

Bu tan45 = 1

So,

tanθ=tan45

θ = 45°

sin45 = 1/√2  cos45 = 1/√2

sin⁴θ+cos⁴θ  = (1/√2)⁴+(1/√2)⁴

                     = 1/4+1/4 = 2/4 = 1/2 = 0.5

Hope this helped you..................
