WebThere's an angle in QII, namely 135 degrees, whose tangent is -1, and there's an angle in QIV, namely 315 degrees (or -45 degrees, if you prefer) whose tangent is -1. In order for arctan to be a function, arctan(-1) must have just one value, and the same has to be true for arctan(x), no matter what real number x stands for.

Arctan - Math

Webarctan2x等于2arctanx吗 对于arctan(tan2x)，它相当于将x替换为了2x，所以同理可得arctan(tan2x)=2x。 但是对于arctan(2tanx)，其涉及反三角函数的二倍角公式，已经超出了大学高等数学的计算范畴。 WebArctan definition The arctangent of x is defined as the inverse tangent function of x when x is real (x ∈ℝ ). When the tangent of y is equal to x: tan y = x Then the arctangent of x is equal to the inverse tangent function of x, … polyester wadding manufacturer
