Differntiate a list of functions of and auomatically compile a LaTeX document to view the results.

handyderivatives

This is a command line program to get the derivatives for differentiable functions of a single variable.

Installation

pip install handyderivatives

https://pypi.org/project/handyderivatives/

Running it

To simply print back to the terminal.

handyderivatives -f functions.txt

To automatically compile a LaTeX document with pdflatex

handyderivatives -f functions.txt --latex

How the input file should be formatted

Edit a file that has functions listed one per line. The left hand side should be what your function will be differentiated with respect to, i.e f(x) . The right hand side will be the expression.

# This is how the file for the argument -f should be formatted.

c(x) = r * (cos(x) + sqrt(-1) * sin(x))
a(t) = 1/2 * g * t ** 2
f(x) = sin(x**2) * x^2
h(w) = E ^ (w^4 - (3 * w)^2 + 9)            # Capital E is interpreted by sympy as the base of the natural log.
g(x) = exp(3 * pi)                          # So is exp(x), but written as a function taking an argument.
p(j) = csc(j^2)

If you don't format it like that you will likely run into errors. You can add comments
