I need the formulas for calculating log, Exp and atans when all I have available to me is the sin, cos, tan functions. The backstory is that I am porting source code from a language that has a full Math library to a language that only offers sin, cos and tan. Thanks.

i need to find the area under the curve of x^3 for 8 partitions, between x=0 and x=2. teh formula is (1/4k)^3(1/4) for 8 partitions, but when i use the ti-86, (sum(seq(function,variable,beginning,ending,increment) i get a number around 17 instead of 4, which is the correct area. why?
