We found the same result by using trigonometric functions in Python. Trigonometry is one of the most important parts in engineering and many times, therefore matplotlib.pyplot in combination with NumPy can help us to plot our desired trigonometric functions. The method returns the inverse of tan, so that if y = tan (x) then x = arctan (y). np.log, np.log2, np.log10: array NumPy has a standard deviation function, np.std(), but here well write our own that works on a 1-d array (vector). As shown above, it returned value of cos at pi/1. To calculate the inverse of tan in Python, we use math.atan () function. NumPy provides vectorized functions for elementwise evaluation of many elementary mathematical functions and operations. To find out the inverse of sine or arcsine in Python we use math.asin() function or Standard math Library. It has an inbuilt function name deg2rad() which can directly convert degrees to radians. NumPy provides the ufuncs sin (), cos () and tan () that take values in radians and produce the corresponding sin, cos and tan values. Note: 2pi Radians = 360 degrees The convention is to return the angle z Before we discuss about numpy trigonometric functions, numpy hyperbolic functions, numpy inverse trigonometric functions, lets create one numpy array first.. numpy stands for numeric python which is used to perform mathematical operations on arrays.. sum (a[, axis, dtype, out, keepdims]): Sum of array elements over a given axis. Calculate Inverse of Cosine Using Python NumPy Library. Arc tangent is also defined as an inverse
