Xeda, Is there a way for you Jonbush or Timothy to check the ip? And yes, the writing is identical and very unique.
Myles, Calculus doesnt actually require a calculator. Integrals and derivatives are all algebraic manipulation, and then to solve it is substitution. It does get a bit tricky to do anything with more than a power higher than a cubic; and the trig functions sometimes are tricky although the problems are usually formulated such that the answers to the trig functions can be obtained from the unit circle (which we were required to memorize in high school pre-calc). I have conpleted calculus 1 and 2 and will be completing calculus 3, calculus 4, and differential equations next year.
Battlesquid, thanks for the cheers! Cheers mate!
