prepare a report which contains the C source code, the documentation and the flow charts, along with drawings explaining the mathematical background related to the calculation of-

insertCode:F(x)= 5.x^2 + e ^(1/2.x) / 1/3.x^2+25.x+1.6

in the range x ∑{A,B}

With a step of B-a/y, e.g. y= 1000.

The range, i i.e. a,b along with the step discretisation should be user defined. The results of the calculation should be stored in a file in the current directory which is also user defined.

in a second independent program, calculate the area (integral from a to b)

f (x).dx for the discrete value of an f(x) passed to the program through a user defined file located in the current directory. The output of the previous program

in a third independent program calculate f`(x)= dy/dx for all values provided the output file of the first prgram with the assumption that dy/dx= ∆y/∆x, ∆x→0

How would I do this? I have taken a c language class but have never did equatons or mathematical operations, also how do flow charts work?
