How to find tension given pulse equation?

A transverse pulse is propagating on a 2.0 m long string of mass 50 g. The pulse is
described by the equation:

y(x,t)=pi/(pi+(3x/2+pi(t))^2)

, with x and y in meters, and t in seconds.
Find the tension in the string.

The equation to use that relates tension in the string to velocity of propagation is:



You can take the time derivative of your y(x,t) formula to find v as a functioj of x and t. However, I must say your equation is a bit confusing. What you wrote is this:



Do you really mean to suggest that pi is a function of t?
