Question

I need a simple program in C language that calculates the values of Sine, Cosine, and Tangent of values given in degrees. It has to be a range of values between 0 and 360(integer values). The output should be a table of values showing Sin, Cos and Tan values. The complete computation and printing of the table must be done inside a function. The function also returns to the main program with 3 output arguments: It also needs to show the number of negative values for Sin, the number of negative values for Cos, and the number of indeterminate(undefined) values for Tangent (typically these are infinity values. For the purposes of this program they will be anything outside the -100 to 100 range).

The main program should prompt the user to enter 2 integers in the range of values to be computed. Making sure that the user does not enter a range outside of 0 and 360. If they do, the program should display an error message and ask them to re-enter 2 numbers. After the user enters a pair of valid integers, the program stops, there is no need to loop to ask for more inputs as long as both inputs are valid. Also, the program should not allow the user to enter inputs with a range of more than 90 degrees (ex. 0 and 90; 90 to 180, 170 to 240, etc.).

After the function is called to print the table of values, the printing 3 additional items (# of negative values for Sine, Cosine and undefined values for Tangent) must be done in the main program (not in the function where they are computed).

The function needs to have 2 integers as input arguments (for range). The function does not return any value (void function) but has 3 output arguments (pointers to integers) one for the total count for each of the items mentioned above. The function has to use a FOR loop to compute the range of Sine, Cosine, Tangent values from the smallest to the largest in increments of 5 (It can use the Math library functions sin, cos and tan). The printing of all the table of computed values must be done inside the FOR loop (in the function). The function can have any other print statements as needed to be able to print a clean, well-aligned table of values with a heading for each column.

Output should look something like this...

This program finds the Sine, Cosine and Tangent values for angles between 0 and 360 degrees Please enter the start and ending values (between 0 and 360 degrees) for computation Sine, Cosine and Tangent for degrees 0 to 90 in steps of 5 0 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 90 Sine: 0.0000 0.0872 0.1736 0.2588 0.3420 0.4226 0.5000 0.5736 0.6428 0.7071 0.7660 0.8192 0.8660 0.9063 0.9397 0.9659 0.9848 0.9962 1.0000 Cosine: 1.0000 0.9962 0.9848 0.9659 0.9397 0.9063 0.8660 0.8192 0.7660 0.7071 0.6428 0.5736 0.5000 0.4226 0.3420 0.2588 0.1736 0.0872 0.0000 Tangent: 0.0000 0.0875 0.1763 0.2679 0.3640 0.4663 0.5773 0.7002 0.8391 1.0000 1.1918 1.4281 1.7320 2.1445 2.7475 3.7320 5.6712 11.4299 XXX o nooo na a 96 08 10 Number of Negative Sine values: 0 Number of Negative Cosine values: 0 Number of Indeterminate Tangent values: 1
