## 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!## Homework Statement
