  1. Hi! I was trying to analyse the RC series circuit for a sinusoidal AC input. I fed the input with an AC voltage V1sin(wt), and found the differential equation for the voltage across the capacitance Vo. RC dVo/dt +Vo = V1sin(wt) I assumed the capacitor was chargeless, so Vo = 0 at t=0. Next I tried to solve for Vo using two methods. I used Laplace transform and brute-force solving the differential equation itself. However I arrived at two different results, considering the same initial condition. Please see if I'm missing something. Or do give an explanation. I know it's very trivial, but this is getting on my nerves. PS: I didn't know the right category for this question so posted under Engineering. I am so sorry. It was a mistake. Please take back the post.
  2. Trump is another epitome for the rising trend in aggressive ethno-nationalism in politics. His most popular slogan "Make America Great again" and bullying others, including activists, social workers, leftists, and even non-whites is something that will instantly portray him as a white supremacist. There was a surge in the white supremacist groups and hate groups in US in his regime. He also totally destroyed America's diplomatic relations. He often quotes false statements in press conferences, and many popagandas. He did nothing to help people in the covid pandemic. Indeed he was not deserved to be a President.
