The tangent function is one of the main six trigonometric functions and is generally written as tan x. Its formula is tan x = Perpendicular/Base = Sinx/cosx
进一步，tanx的泰勒展开式可以表示为tanx=x+x^3/3+2x^5/15+17x^7/315+62x^9/2835++[2^(2n)*(2^(2n)-1)*B(2n-1)*x^(2n-1)]/(2n)!+。（|x|<π/2）
tan(A−B)=tanA−tanB1+tanAtanB Step 1: Identify A and B We can express 15∘ as 45∘−30∘. Thus, we set:- A=45∘- B=30∘ Step 2: Calculate tanA and tanB We know:- tan45∘=1- tan30∘=1√3 Step 3: Substitute into the formula Now, substituting A and B in...

The basic formula to determine the value of arctan is θ = tan-1(Perpendicular / Base). Is Arctan the Inverse of Tan? Yes, arctan is the inverse of tan. It can determine the value of an angle in a right triangle using the tangent function. Tan-1x will only exist if we restrict...
Instead, the arctangent formula is usually evaluated using a scientific calculator. On most scientific calculators, the arctangent function appears as a secondary function to the regular tangent function. It's labelled with the {eq}\tan^{-1} {/eq} symbol rather than {eq}\arctan {/eq}. Af...
This article describes the formula syntax and usage of theTANfunction in Microsoft Excel. Description Returns the tangent of the given angle. Syntax TAN(number) The TAN function syntax has the following arguments: NumberRequired. The angle in radians for which you want the tangent. ...
Tangent Formula The tangent formula is: tan(α) =opposite/adjacent=a/b Thus, the tangent of angle α in a righttriangleis equal to the opposite side’s length divided by the adjacent side’s length. To find the ratio of tangent, simply enter the length of the opposite and adjacent and...
tan的半角公式：tan(α/2)=±√((1-cosα)/(1+cosα))。半角公式（Half angle formula）是利用某个角（如∠A）的正弦值、余弦值、正切值，及其他三角函数值，来求其半角的正弦值，余弦值，正切值，及其他三角函数值的公式。三角函数是基本初等函数之一，是以角度（数学上最常用弧度制，下同）为自变量，...
