getting red line under sqrt and atan in c++ 2010


f_mag= sqrt((fx)^2)+((fy)^2);
theta=atan((fx)/(fy));

[18hRX9L8]

Well for power use pow() function. Also, make sure that fx and fy are floats. And include <math.h> or <cmath>.

atan is correct now but pow is under red line

[Chervil]

What does your call to pow() look like, and what are the types of the variables or values used? Please show the code.

@sweetgirl

How are you getting along with the advice I gave you?

Why are you working out f_mag & theta - you already have those, the assignment is asking for the sum of the X & Y values.
