How do you solve a Differential equation for beginners

Click For Summary
SUMMARY

The discussion focuses on solving the differential equation \(\frac{dy}{dt} = t^2 y\). Participants outline the steps to rearrange the equation into \(\frac{1}{y}\frac{dy}{dt} = t^2\) and emphasize the importance of integrating both sides with respect to \(t\). The integration leads to \(\int \frac{1}{y} dy = \int t^2 dt\), which is a critical step in finding the solution. The conversation also highlights the need for understanding integration rules and suggests seeking educational resources for further learning.

how do you solve a Differential equation ?

for example how do you solve this

d/dt y(t)=t^2 y(t)

step by step help would be appreciated where + w2x = 0 is suppose to be in between d^x and dt^

What are [ U] and [ /U] tags ?

Use [ tex] and [ /tex] for latex. The equation is not visible.
 
What you want to solve is
\frac{dy}{dt}=t^2y
You can rearrange this into
\frac{1}{y}\frac{dy}{dt}=t^2
You can now integrate both sides with respect to t.
 
how do you integrate it ? please tell me how
 
\int \frac{1}{y}\frac{dy}{dt} dt= \int t^2 dt

and this is the same as:

\int \frac{1}{y}dy= \int t^2 dt

Can you integrate this now?
 
\int \frac{1}{y}dy = \int t^2dt

And carry on from there.

Whoops, someone beat me.
 
what are the rules of integrating
 
You can look up integration rules on the internet. Integrating is undoing the derivative, ie. finding the antiderivative.

wheres the best site to learn it from ? where did you learn it from

I learned it through a high school calculus course. If you don't know how to integrate, I suggest you ask your professor/teacher.
