1 INITIAL-VALUE PROBLEM

Solve the initial-value problem: dv/dt -2tv = (3t²)(e^t²) ,v(0) = 5 Thanks in advance!-The equation is first order linear. Use the integrating factor exp(∫ -2t dt) = e^(-t²). Multiply through a

An example of a function f that is not Riemann integrable but |f| is Riemann integrable

Im trying to think of an example where this happens so that I can practice showing that a function is or is not Riemann integrable, and thought this would be an interesting case to try. But I cannot w
