Answer 2

Answer:

Given: sinx + sin²x = 1

We know that by trigonometry identity ,

sin²x + cos²x = 1

Therefore , By Given

sinx + sin²x = 1

sinx + sin²x = sin²x + cos²x

by transfer method,

sinx = sin²x + cos²x - sin²x

sinx = cos²x

Put the value,

cos²x + cos⁴x = sinx + (sinx)² Where, cos⁴x = (cos²x)²

= sinx + sin²x
