1. Write a program that will calculate the arc sine (that is, sin™?) of
a value that has been keyed into the displayed X-register. Test
the resulting angle with a conditional, and if it is negative or
zero, add 360 degrees to it to make the angle positive. Use the
flowchart below to help you write the program.
