Question

please answer my question guys...

Answer 1

Answer:

1/2

Step-by-step explanation:

Given Equation is sinθ - cosθ = 0.

⇒ sinθ = cosθ

⇒ sinθ/1 = cosθ

⇒ (sinθ)/(cosθ) = 1

⇒ tanθ = 1

⇒ tanθ = tan45

⇒ θ = 45°

Now,

sin⁴θ + cos⁴θ

= (sin 45)⁴ + (cos 45)⁴

= (1/√2)⁴ + (1/√2)⁴

= 1/4 + 1/4

= 2/4

= 1/2

Hope it helps!
