invalid operands of types ....

Hello, I'm getting the following error on line 39 with my code but I really don't see what's wrong :(.

error: invalid operands of types 'double*' and 'double' to binary 'operator*'

On line 39 you're trying to multiply r, which you declared on line 15 as a pointer to a double, by sin(theta[i]), which is a double. Perhaps you meant r[i] instead.
