Homework Statement
A Transverse wave on a string is described by this function :
y=.25(meters) sin[[tex]\frac{\pi(4)}{8}[/tex] + [tex]\pi[/tex]4t]
a.) Find the speed of the wave at t= 2sec
b.) Find the acceleration at t= 2sec
Homework Equations
y=.25 sin[[tex]\frac{\pi(4)}{8}[/tex] + 4[tex]\pi[/tex]t]
The Attempt at a Solution
I tried taking the derivative with respect to t, but man I can't figure it out for the love of god and I have no idea what I'm doing wrong. I doubted myself so much I don't even know if I need to take the derivative.
P.S. at the end of the equation its 4 * pi * t (not 4 to the power of Pi) and its .25 meters
