1. The problem statement, all variables and given/known data THe x and y axes have been rotated about the origin through a 45 degree angle to produce the X and Y axes.. Thus, a given point P (x,y) has coordinates in the first coordinate system and (X,Y) in the new coordinate system The orignal equation is y=10sech(x). What is the new equation in the new coordinate system? 2. Relevant equations 3. The attempt at a solution x= X cos(theta) - Y sin(theta) y= X sin(theta)- Y cos (theta) These are for individual points but not for whole equations.
