I am having some trouble figuring out how to create the loop I need. Whenever sin[a] != 0, I want the loop to add a random number to a and then evaluate sin[a + random number] to see if it equals 0. If sin[a + random number] != 0, I want the loop to add another random number to the sin argument and evaluate that to see if it equals zero, and so on until it is zero. Then I want to print the number of random numbers I had to add to get sin = 0.

I want to start at a = 90 degress. I was thinking something like:

a=90 degress; If[Sin[a] != 0, a += RandomInteger[{0, 360}], Print[i]]

where i++ each time a random number is added. Thanks.
