Write a method called eTaylor that takes as input (i.e. argument) a double x and returns the value of e. This method should NOT use any Math library functions, so you will need to use Taylor Series for e (loop until terms become close to 0, say 10e-16): ex = 1+1.LT+-... Hint: Write a helper method for finding the nth power of a number x, divided by n! n. (n -1) . (n -2).....2.1 that is, your helper method should accept an x and outputYour method eTaylor vwill return the value of n=0 n! Hint: Try theseries at least to the point where n = 5, n = 10 and n = 20
