# How to import equations from a pdf

Here is a pdf I am trying to import: https://i.stack.imgur.com/J2e0z.png

Its a photo so that I can upload it here easily. I am trying to extract the formulas from this pdf but to no avail. Plaintext returns me something that is not easy to work with. Is there a way of doing it or am I doomed to do it by hand?

Any help would be appreciated.

• am I doomed to do it by hand I think so. This is a task that needs an AI or neural network to read the math equations from the images, and convert them to Mathematica correct syntax. Mathematica as I understand has advanced neural network functions. May be you could build one and train it to read these images and convert them to Mathematica code. But I do not think this is an easy task. Wolfram NeuralNetworks.html Oct 22 '21 at 3:49
• @Nasser NeuralNetworks are certainly beyond me. that is unfortunate. Thank you! Oct 22 '21 at 3:54
• They are beyond me as well. if I were you, I'll just translate them to Mathematica by hand. it might take 30 minutes or so. Oct 22 '21 at 4:05

• Do you know how to derive these equations? It might be easier to program this in MA. Oct 22 '21 at 18:59

• There is also this post on TeX SE: State of generating $\LaTeX$ from handwriting.
• @gwr there are few such apps. For example Maple has one that is supposed to Enter handwritten and typeset math problems at the click of your camera using powerful AI technology and Validate handwritten solutions in Maple Learn  here is the link MapleCalculator how good they are? I do not know as I never used any of them. I doubt they are good for any complicated math equation unless the AI is very good. I think this is all just marketing. Oct 22 '21 at 8:54
