Product to Sum Trigonometry Identities Calculator

Calculate Product to Sum Identities

Unlock the power of trigonometric identities with our Product to Sum Calculator. Easily convert complex expressions like sin A cos B or cos A cos B into simpler sums, streamlining your mathematical problems. This tool is essential for students, engineers, and anyone needing quick, accurate trig formula conversions for any given angles.

Formula:

The calculator uses the following fundamental Product to Sum Trigonometry Identities:

  • 2 sin A cos B = sin(A + B) + sin(A - B)
  • 2 cos A sin B = sin(A + B) - sin(A - B)
  • 2 cos A cos B = cos(A + B) + cos(A - B)
  • 2 sin A sin B = cos(A - B) - cos(A + B)

Where A and B are the input angles, which can be in degrees or radians.
