Reduce each of the following expressions to the Sine And Cosine of A single expression:

Let f(x) = √3 sin x – cos x


Dividing and multiplying by √(3 + 1) = 2,



Sine of expression:



We know that sinA cosB – cosA sinB = sin(A –B)



Cosine of the expression:



We know that cosA cosB – sinA sinB = cos(A +B)
