Math Transforms
Math transforms perform a transform function (like differentiate, integrate, FFT, or square root)
on a voltage, current, or power signal or on an add, subtract, multiply, or divide math waveform.

Differentiate
The d/dt (differentiate) transform calculates the discrete time derivative of the selected source.
You can use differentiate to measure the instantaneous slope of a waveform.
The d/dt transform plots the derivative of the selected source using the "average slope estimate
at 4 points" formula:
Where:
d = differential waveform
y = Channel or Math data points
i = data point index
Δt = point-to-point time difference
