Homework Statement
(theta)= 45Degrees
Homework Equations
(theta)= Arctan(y/x) (x>0)
(theta)= Arctan(y/x) (x<0)
The Attempt at a Solution
Tan(45)=y/x
1 = y/x
Does that mean Y = X?

Yes, it does! If you are not convinced, draw an xy- coordinate system, mark the line at 45 degrees to the positive x-axis and draw the line y= x!catteyes said:Homework Statement
