Given here is the trigonometric identities sine addition formula for the calculation of sine of sum of two angles. The addition formula can be used to solve various trigonometric equations and help transform the equation into other equivalent forms. The formula remain true for all values of the two angles. The trigonometric sine addition formula can be useful to simplify a complicated expression, or perhaps find an exact value when you only have a small table of trig values.

Where,

a = Angle 1

b = Angle 2

Trigonometric Identities Sine Addition Formula is given for you to clearly understand for the calculation of the sum of two sine angles. Make use of this formula to find the Sin(a)+Sin(b) calculation and solve various problems based on this formula.
