 Homework Statement
 a stretched spring is given simultaneous displacement in the x and y directions. what is the resultant displacement and angle ?
 Homework Equations

x = acos(2*pi*z/lambda  2*pi*w)
y = a sin(2*pi*z/lambda 2*pi*w)
If I take the vector sum, I am getting the angle to be 1. (tan^1 tan(1)). Is that correct?
