(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A sin (wt + [tex]\Phi[/tex]) = 0

Find A and [tex]\Phi[/tex]

2. Relevant equations

Asin(wt)cos[tex]\Phi[/tex] + Acos(wt)sin[tex]\Phi[/tex] = 0

3. The attempt at a solution

I was told to use magnitude to figure out A and something else to find [tex]\Phi[/tex] in variable.

I absolutely have no idea what to do...

I found a part of solution, which got me w and I am expected to solve for A and [tex]\Phi[/tex] with that given equation.

I tried to use original equation by plugging in t = 0 for A sin (wt + [tex]\Phi[/tex]) and first and second derivative from original equation.

I think once I get those A and [tex]\Phi[/tex], I "might" be able to solve entire problem.

Thank you.
