what is value plz answer​

Answer 1

Answer:

the answer is your question is 1

Answer 2

forumla used

A³+B ³= (A + B)(A²-AB +B ²)

solution

sin³x + cos ³x

= (sinx + cosx)(sin²x -sinx cosx +cos²x )

= (cosx + sinx)(1 - cosxsinx)

$= ( \sin(x) + \cos(x) ) \times \frac{1}{2} (2 - 2 \sin(x) \cos(x) )$

$= \frac{1}{2} ( \sin(x) + \cos(x))(2 - \sin(2x) )$

i hope it helps you!
