sum formula for tan 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
Angle addition formulas express trigonometric functions of sums of angles alpha beta in terms of functions of alpha and beta Finding the sum of two angles formula for tangent involves taking quotient of the sum formulas for sine and cosine and simplifying Recall tan x sin x cos x cos x 0 tan x sin x cos x cos x 0 Let s derive the sum formula for tangent

Using the sum formula of tangent function we have tan A B tan A tan B 1 tan A tan B Substituting A B on both sides here we get tan 2x tan x tan x 1 tan x tan x 2 tan x 1 tan 2 x In this lesson we want to find a formula that will make computing the tangent of a sum of arguments or a difference of arguments easier As first it may seem that you should just add or subtract the arguments and take the tangent of the result However it s not quite that easy
We will begin with the sum and difference formulas for cosine so that we can find the cosine of a given angle if we can break it up into the sum or difference of two of the special angles First we will prove the difference formula Using the sine and cosine of the sum or difference of two angles we can prove tan x y tan x tan y 1 tan x tan y Created by Sal Khan
