3. The polar coordinates r and 6 of a point (2,y) in the plane can be computed as follows: r= V12 + y2 0 = acos(/r) -acos(x/r) 0 if r> 0 and y> 0 if r> 0 and y #include #include #include using namespace std; /* function prototype */ int main(void) { float x, y r, theta; /* You fill in here */ return 0; } /* function definition */ Note: Rule regarding pass by reference: When deciding how to pass function arguments: if the argument must be changed by the function { pass by reference } else { pass by value }
