Title: S2.3 Problem 8
Post by: MikeMorris on January 27, 2019, 06:42:08 PM
In this question, the initial conditions are not given for $t = 0$, as we've discussed in class, but instead for $t = \frac{x^{2}}{2}$. I have no idea how to approach this. Could someone please help?

Find the general solution and then plug to initial conditions

Hello professor, could u give me a hint as to why we have to impose the restriction for absolute value of x to be smaller or equal to 1?

Draw characteristic lines and plot $t=x^2/2$
