Hey Forum!!! This is my first post. I came across this board while looking for help on how to start learning calculus. I am interested in this topic because I recently bought a Casio FX-CG50 calculator and I would like to be able to use it for something entertaining and also educational--drawing curved line graphs and the like. The 'Polar Graphs' it is supposed to be able to draw are especially impressive! According to the manual many of these functions are designed for helping with calculus problems, so this seems like a good place to start! I do recall very vague lessons on calculus during 'A' level further maths way back in my school days but I am drawing a total blank on what 'differentiation' and 'integration' mean as such, much less the all the rest of the jargon. Hence I would really like a place to start learning and I wonder if any of you chaps could suggest perhaps a book or a website that would make it easy for a beginner to get stuck in? Also, maybe the FX-CG50 isn't the best box for the job? I have seen both the 'HP Prime' and the 'Nspire CX CAS' recommended on Amazon for calculus, so maybe I should pick up one of those as well to help with the process? Anyway, many thanks for any suggestions you may have.
