SymPy is REVOLUTIONARY For Mathematical Tasks

Today we talk about SymPy, which is a mind-blowing module for those of you who are into mathematics and need to work with equations and formulas on a regular basis.

when sympy returns sqrt(15) it's not just because it's convenient, but it's exact. whereas math returns an approximation

My favorite feature is being able to convert an expression to LaTeX.

This is one of the best python related channels out there. The stuff I've learned from this channel in 10 mins...

Great intro to sympy. There is a small typo in the limits example with 50/x. You wanted to show the behaviour for x -> infinity but typed 00 instead of oo.

[brandonscott]

Thanks for the content. Always appreciate people trying to provide education to the world. Hope your channel is a success. 👍

Great Video! If you execute the exact same lines in a Jupyter notebook, you automatically get the Latex output, which is super nice. Instead of like "x**2+ x**3" in the console, you get the actual resemblance of math notation like in text books etc.

Sympy is fantastic, I use it a lot, specially for automatic code generation. Every student, no matter the level, should learn it. It could be a bit faster, but I understand they are already working on it.

How do you find those awesome libraries?
Intentionally searching from web documentation or you had already a list that you are picking and working on it?
I have my respect for you and your channel and you are doing a fantastic job. But I would like to get your mind set as well :)

Makes me fall in love with math again. Pretty cool. Thanks for sharing this.

[Chalisque]

The limit(50/x, x, 0) example should only return +oo if 0 is approached from the positive direction.

[pjmmccann]

My favourite piece of this was the "...mumble, mumble, mumble, ACCUMULATED BOUNDS [-2, 2], mumble mumble..." when trying to get sympy to evaluate the integral of sin(x) between -oo and oo (which doesn't actually exist, of course). No explanation, just head down and carry on 😂.

[dmitrykononenko]

thanks for review, i didn't know about this useful library

[jedi]

the purpose of symbols is if you have multiple symbols you can do it in one line.

like your 2 line assignment
x = symbols('x)
y = symbols('y')

should just be
x, y = symbols('x y')

[shreenivasn]

An amazing thing is Jupyter Lab displays the output in mathematical font, unlike output we get in this video

[miketan]

I was not aware of this phython library, thanks for showing. I can’t focus on the result sometimes because it is there for such an extreme short time.. to stop all the time the video breaks the whole story

[oldschoolgaming]

damn, I wish you posted this like, a month ago.. :D
That said, great content as usual, never dissapoint. Keep up the good work!

[Freeflier]

Sympy is better in the interactive terminal or juypter notebook when it displays mathjax outputs

[timezcooler]

This is great since im losing all my matlab modules (including the symbolic maths one) once im graduate and lose my school email

[Mekuso]

Sympy is conceptually awesome but in practice it is barely useable. It fails to compute even fairly simple derivatives of matrix expressions, for example, that Matlab's symbolic toolbox handles in a few minutes.

[edgostyn]

Where are the constant when evaluating an integral?
