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.

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.

Today I learned the concept of hashing and hashmapping.

it's true !!

Today I learnt how to find the inverse of a matrix. Interesting!

Today I learnt how to solve second order linear non homogeneous differential equations. ;-)

Hi, paragaster are you an Indian? Or Hindu researcher?

It will be great if there is an SFN app for smartphones.

A good poem. +1

I want a Hand I want a hand that is not so deceptive as the weather; I want a hand that is not so light like a feather; I want a hand that is not as false as stairs of sand; I want a hand that is not violent like a terrorist band. I want a hand that is devoid of jealousy and cruelty; I want a hand that is the true sign of love for humanity; I want a hand that bears no greed; I want a hand that supports me in my times of need.

Today we are living in a world where the buzz of modernization has led us to breathe polluted air in. I have written a poem (I do not claim it excellent, but have tried my level best) to spread awareness about prevention of pollution and saving our planet. Save the Environment How do you feel when your things are damaged And your house is raided? Then, why don't you understand It's important to conserve the air, water and land. They are your property in every way - You use them everyday. If you waste a liter of water each day It will kill the fishes one day. If you throw a plastic bag carelessly It will destroy life too carelessly. If you liberate smoke and toxic gases into the air It will cause global warming. So take care. Conserve your planet and your environment; Play a part to protect the beauty of natural environment. Let us take a pledge together - A tree will be cut never; Let us plant trees more and more To save our life and the nature's core.

:-)Hi, It is the habit of many people to use their leisure in writing poetry. Everyone is not a poet, but the feeling of writing poems can be experienced by anyone. So, let's start a new Poetry Section.......anyone can post his/her poems here.
