There’s one small detail to be careful about when using the arctangent function, though, which led many programming languages to develop an alternative implementation called atan2(). Calculating the ratio betw
cotx:周期派 反三角函数(Inverse Trigonometric Function) 1.sinx反函数(arcsinx) 如上图:sin x 不是单调函数,所以它整体没有反函数; 但在[ -90度,90度 ] 即 [ -π/2,π/2 ],是单调的,可以求此区间反函数; y=sin x => x = arc sin y arc代表:当前函数的反函数 反函数图: sinx和arc sin x ...
Return the inverse tangent of x. math.atan2(y, x) Return the principal value of the inverse tangent of y/x. math.atanh(x) Return the inverse hyperbolic tangent of x. math.ceil(x) Return an integer, being x rounded towards positive infinity. math.copysign(x, y) Return x with the sig...
ATANH : Inverse hyperbolic tangentCEIL : CeilingFLOOR : FloorERF : Gauss error functionNOT : NotSIGN : Sign. If input > 0, output 1; if input < 0, output -1; if input == 0, output 0.ROUND : Round to nearest even for float datatype....
Logarithmic functions can be considered the inverse of exponential functions. They are denoted in the following form: General Logarithmic Function Here a is the base of the logarithm, which can be any number. You learned about exponential functions in a previous section. Exponential functions can ...
