In Maple and Mathematica, how do I convert sin(A+B) to sinA cosB + cosA sinB, and vice versa?
sinA cosB + cosA sinB
and vice versa in Maple or Mathematica, use the appropriate commands
Mapleexpand(sin(A + B)); combine(sin(A)*cos(B)+cos(A)*sin(B), trig);
MathematicaTrigExpand[Sin[a + b]] Simplify[ Sin[a] Cos[b] + Cos[a] Sin[b] ]
