Homework Statement
Hey everyone,
I've data for some oscillatory motion. I used MATLAB to find line of best fit for the data. I got a line of the following form
y = A*sin(2*pi*f*t + ø)
I got the root mean square error between my data and the line of best fit (call it u_y)
Now I want to differentiate the above equation to get the velocity
V = dy/dt.
How do I get the uncertainity for V?
The Attempt at a Solution
I'm really stuck. I'm trying to use Kline Mcclintock error propagation to solve for uncertainty of the Velocity.
V = dy/dt
u_v = √( (dv/dy * u_y)^2 + (dv/dt*u_y)^2 )
Is this the right approach??
