ArcTan is the inverse tangent function. Best Regards Pradeep. For real values of X in the interval [-1, 1], acos (X) returns values in the interval [0, π]. Using special angles to find arccos. Follow this answer to receive notifications. 5. If you need to, you can adjust the column widths to see all the data. Make Sample of calculation for crank angle of 30 degrees. You need to use atan, not arctan: >> atan (7e8/1.5e14) ans = 4.6667e-006. Calculate m (slope) of a line given the angle in degrees. asind (1.0019) you are asking for the angle (in degrees) whose sine is equal to 1.0019. Sometimes sin-1 is called asin or arcsin Likewise cos-1 is called acos or arccos And tan-1 is called atan or arctan. For real values of X, atan (X) returns values in the interval [-π/2, π/2]. In mathematics, the inverse trigonometric functions are the inverse functions of the trigonometric functions. We are given the opposite and adjacent sides. θ = Sin-1 (Opposite side/Hypotenuse) Let us see an example of inverse of sine function.
