Trigonometric functions, such as sine...

Trigonometric functions, such as sine and cosine are normally evaluated on computers by using a truncated infinite series. The same approach is used to compute the inverse of these functions.

For instance, a truncated series used to calculate the cos of an arbitrary angle x is

cos x=1-(x^2/2!) +(x^4/4!) - (x^6/6!)+.....+(-1)^n (x^(2n)/(2n)!)

and, k! = 1x2x3x......x k

in which x is in radians. Write a program in VB that allows user to enter values x and n. Then the

program calculates cos(x) by above formula using n first terms of the series and a DO LOOP. Using

your program find and report values of cos30 and cos60 for n=2, 4, and 5.

Develop a ‘Windows Forms’ application which allows user to enter values of n

and x via a graphical interface, and calculates/dispays cos(x) when ‘Calculate’ button is clicked User can exit the program by clicking ‘Exit’ button.
