Question

Find the value of
Sin(45-alpha) - cos (45+alpha)
Need the answer as soon as possible

Answer 1

sin(45-x) - cos(45+x)

We know,

Sin(theta) = cos(90°-theta)

So,

sin(45-x) -cos(45+x)

=>cos(90-(45-x) -cos(45+x)

=>cos(90-45+x) - cos(45+x)

=>cos(45+x)-cos(45+x)

=>0

{I have taken x in place of alpha}

So,

sin(45-alpha)-cos(45+alpha)= 0

Cheers!
