Question

This is a differential equation of 2nd order, I need to find a function that if substituted on both sides will be equal
d2xdt2=−ω2x

Answer 1

\[\frac{ d ^{2}x }{ dt ^{2}} = \omega ^{2} x\]

Answer 2

omega squared, or minus omega squared ?

Answer 3

minus omega squared sry

Answer 4

no problem
suppose you have a function f(x) = sin(x)
what is df/dx ?

Answer 5

0?

Answer 6

No : (

You should read up a bit on differentiating sines and cosines then come back to your differential equation question

Answer 7

Okay will do, thanks anyways :)
