How does

sin(c+h)=sin(c)xcos(h)+cos(c)xsin(h)

please explain

  • Maths-Trig - ,

    What you have here is the sum of two angles, which is:

    sin(c+h) = sin(c)cos(h) + cos(c)sin(h)

    I'm not sure where the "x" comes into play with your equation, is it supposed to be a variable or a multiplier?
