# Division by zero error

## Main Question or Discussion Point

I have data from a pendulum and I am using it to work out the radius of the pendulum. I have acceleration in the x and y directions and so thought this would be easy enough. Simply I determine the (velocity in the x direction)^2/acceleration in the y direction. However when I use python to give me a graph I notice that I get a graph with a large peak at the extremes (ie where the pendulum monetarily stops at the extremes and I am therefore dividing by zero) Any way around this?
