As my first Mathematica assignment, I need to solve and then plot a linear IVP. I understand that I must use
DSolve. However, when attempting to plot my output, nothing shows.
My equation is
$\qquad x\,y'+ 2 \cos(x^2)\,y = 0 \quad y(1) = 2$
I understand that this is not a very difficult problem, but I am struggling to understand the Mathematica way of expressing the problem.
