-Hyperbolic and inverse trig functions
Statistics:
-Min, max, mean, standard deviation, variance
-Easy to use list syntax: stdDev({1,2,3,2})
-Create custom lists: seq(rand*X,X,1,5)
Calculus:
-Calculate the area under a curve: fnInt(2X, X, 1, 2)
-Find a point derivative: nDeriv(X^2+X, X, 0)
-Solve for zeros: solve(X^2 - 2, X, 1.5)
-Complex number operations: conj(), real(), imag()
Linear Algebra:
-Matrices use built in operators, like
