Home Python math Library How to Find Inverse of Tan or Arctan in Python. Enter the sine value, select degrees () or radians (rad) and press the = button. The NumPy library is a widely used library in Python. In order use the sine function sin() in Python we will need to import it from math library (which is built-in).. We will need to convert degrees to radians using . Theme. The method returns the sine of each element of the 1st parameter x. To get the sine value of the angle in radians, need to multiply the angle with np.pi/180. NumPy stands for Numerical Python. In the figure below, the portion of the graph highlighted in red shows the portion of the graph of sin (x) that has an inverse. We can see that each term in the Taylor Series expansion is dependent on that term's place in the series. rel_tol is the relative tolerance - it is the maximum allowed difference between a and b, relative to the larger absolute value of a or b. For instance, if x is passed as a parameter in asinh function (asinh (x)), it returns the hyperbolic arcsine value. -> If provided, it must have a shape that the inputs broadcast to.
