derivative and limit todo list

[Akuli]

• derivative of sin and cos, with and without location and speed
• derivatives of exponent functions
• derivative of ln with chain rule (assume that it exists)
• alternative definition of derivative: lim_(t -> x) (f(t)-f(x))/(t-x)
• derivative exists => is continuous
• limits with infinity
  • lim_(x -> oo) aka limit of function
  • lim_(n -> oo) aka limit of sequence
  • lim = oo (define "limit exists" to exclude these cases)
  • how to convert limit rule derivations so that they apply for these as well
• ensure that derivative-vector.html doesn't say "derivative of f" when it should say "derivative of g" (not sure if i fixed this yet)
• finding min and max values with derivative
