Tangent subtraction formula
WebThe important tangent formulas are as follows: tan x = (opposite side) / (adjacent side) tan x = 1 / (cot x) tan x = (sin x) / (cos x) tan x = ± √ ( sec 2 x - 1) WebGiven a triangle and the tangent formula above, we can find the tangent as shown in the following examples. Example: Find tan(θ) for the right triangle below. ... Subtract 360° or 2π from the angle as many times as necessary (the angle needs to be between 0° and 360°, or 0 …
