tan summation formula The Formula Tangent The sum and difference angle formula for the tangent function is Notice the formula has a plus minus sign and a minus plus sign When we are dealing with a sum of two angles the numerator will
The product to sum identities or prosthaphaeresis formulae can be proven by expanding their right hand sides using the angle addition theorems Historically the first four of these were known as Werner s formulas after Johannes Werner who used them for astronomical calculations See amplitude modulation for an application of the product to sum formulae and beat acoustics and phase detector The sum formula for tangent states that the tangent of the sum of two angles equals the sum of the tangents of the angles divided by 1 minus the product of the tangents of the angles
