Arctan tanx/2 等于多少
Web21 feb 2024 · tan(tanx)这种就只能由内而外算，后两个是反函数的性质，比如tanx有：0.25π→1，那么在arctanx就有1→0.25π，因此arctan(tan0.25π)=arctan1=0.25π，tan(arctan1)=tan(0.25π)=1，可以简单的理解为arctan(tanx)=x，tan(arctanx)=x. 但是要注意y=arctanx输出的y只能是（-0.5π,0.5π）,因 … WebArctan calculator; Arctan 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, which is equal to y: arctan x= tan-1 x = y. Example. arctan 1 = tan-1 1 = π/4 rad = 45 ...
