I have yet to see an app support trigonometry. Is recognizing graphs too hard?

That would be a fun project. If you can digitize the graph reliably, you can then take the discrete Fourier transform of the data, apply some denoising/thresholding to extract the main components. This would tell you if you're looking at sin(x), cos(x), cos^2(x), etc. If you have a training set, you could maybe start picking out more complex functions like abs(x), 1/x, etc.

I am referring to problems like this

I don't think it's easy.
