Simplify: (sin42°)cos38° - (cos42°)sin38°

Question

Help me Simplify the trigonometry equation

Dani K. · Accepted Answer

You are going to need to use the subtraction trigonometric identity.		sin(A-B) = sinAcosB - cosAsinBSo, for this problem:		(sin 42°)cos38° - (cos42°)sin38° = sin(42° - 38°) = sin 4°

Simplify: (sin42°)cos38° - (cos42°)sin38°
