1. The problem statement: What is the value of capacitance needed in Fig. 1 so that the voltage across the capacitor never exceeds (a) 200 V, (b) 20 V, and (c) 2 V ? This is the Circuit Homework Equations Vc(0-) = 0V Vc(0+) = 150V ic = c v' vc(t) = final + [initial -...

Need Help with a couple diff eq problems: 2.) show y=cx^2 - x is a solution of xy' - 2y + x =0 I was trying to separate the variables so i could integrate but i cannot get it to work out. I have tried so many things from adding 2y to both sides and and multiply by the inverse dx/dy. but...
