Finding Zeros of Functions In Python (Bisection Method and Scipy)

In this video I go over two root finding methods in python. I motivate the Bisection Method on paper before getting into how to write a program to implement it. At the end of the video, I show a quick way to find zeros using the fsolve function from the scipy library.

If you replace tol with 0 in the if else statement you get a much better accuracy

You're doing gods work. Please more python videos.

You really got to the root of my issue Andrew, thank you!

[williambrunosalesdepaulali]

Here i am discovering your channel again after so many years hahhas. Awesome!

You can use "elif" instead of nesting "if" inside "else".

I am watching your tutorial in Taiwan. Thank you.

[aliciaroberts]

This really helped me finish my python hw I put off to the last minute, so thank you!

[muhammedabdulmalik]

Great job! You dissected it very well.

[ferns]

Thank you so much!! You made this so easy to understand

[JoseGonzalez-cbgw]

Thank you very much, excellent explanation of the procedure

[brianbecsi]

you call me smart... it goes straight to my head

[bishwasgnawali]

Can you use this method to find a complex root of a complex function?

[danielriquelme]

I like your binary search xD good video

[aureeel]

Please do more python videos, you make it so much easier to understand

[jptuser]

what's the use of the tolerance ??? we did the same code in fortran for computational physics but didn't understand that tolerance

[arthurheinrich]

In the bissection method, if values "a" and "b" are root, or any "c" value makes f() function returns zero, the routine enter in an infinite loop

Could you do Newtons method in Python?

[iamwhitewhale]

do u guys have any idea why my code isn't working? after running the code a star will appear in left side and then nothing, i need to re-run the jupyter.

Did you learn how to use python for physics mainly on your own or did your courses help you develop those skills? I'm going into my Junior year of physics (Quantum and Thermo this year!) and also starting my minor in comp sci, and I have very little knowledge of coding. Been trying to find resources online for learning to code for math and physics and what not, but i've been unsuccessful lol. We do have a course that works with coding for physics at my uni which I'll probably take next semester or next year. Just want to get ahead of the game though to be valuable during research.

Hello! Is there any book or free course that explain numerical methods in a simple way? What do you recommend?
