Homework Statement
Derived the general solution of the given equation by using an appropriate change of variables
5.) du/dt-2(du/dx)=2
Homework Equations
du/dx=du/d(alpha)*d(alpha)/dx+du/d(beta)*d(beta)/dx
du/dt= du/d(alpha)*d(alpha)/dt+du/d(beta)*d(beta)/dt
The Attempt at a Solution
not really sure how to determine du/d(alpha),d(alpha)/dx,d(beta)/dx ,d(alpha)/dt,d(beta)/dt
book says alpha=x+2t, beta=x
