You can use this program to calculate the limited integration value of any mathematical function in any format and with different accuracies, and also the differential value of any function at a point. It can also calculate surface area, volume around x-axis, volume around y-axis and length of any curve know in x-y plane. It supported also custom accuracy input for advanced users and can evaluate the integration in 2 methods. Program supports ALL mathematical functions like sin, cos, tan, arcsin, arcos, arctan, sinh, cosh, tanh, sinh-inv, cosh-inv, tanh-inv, ln(),log10(),exp(), sqrt(), x^n :for all n values ,absolute(), all powers expressions (e.g. f(x) = (2pi)^(2x)). All with a very simple interface. The program is very helpful in education or research purposes.
