Question

Write the expression as the sine, cosine, or tangent of an angle.

sin 48° cos 15° - cos 48° sin 15°

Answer 1

sinA cos B - sin B cos A = sin(A-B)

Answer 2

in this case, A=48 and B=15

Answer 3

@RadEn
so sin33?

Answer 4

yes, that's right

Answer 5

but if u remember the identity :
sin(90-x)° = cos(x)°
so, sin33° = sin(90-57)° = cos57 °
thus, u have 2 answer's
