Description

This project is to write the two functions that compute the derivative of a function.

The function below calculates a spline curve defined by six points

I need to calculate the 1st and second derivative of yt

Function 1: ytd1 = the 1st derivative of yt
Function 2: ytd2 = the 2nd derivative of yt

t= range from 0 to 1

Function:

b1=(1-t)^5
b2=5*t*(1-t)^4
b3=10*t^2 * (1-t)^3
b4=10*t^3 * (1-t)^2
b5=5*t^4 * (1-t)
b6=t^5

xt=(b1*px1)+(b2*px2)+(b3*px3)+(b4*px4)+(b5*px5)+(b6*px6)
yt=(b1*py1)+(b2*py2)+(b3*py3)+(b4*py4)+(b5*py5)+(b6*py6)

Sample inputs:

px1=0
px2=20
px3=40
px4=60
px5=80
px6=100
py1=0
py2=0
py3=0
py4=100
py5=100
py6=100

Dear Buyer I develop and host Graphing and Engineering calculators at http://www.britishcomputercolleges.com . One of them is a Differential Grapher for f(x) which computes f'(x) and f''(x) . It uses the values for differentials to draw a graph. You have presented parametric curves in your proposal and with a little work I will be able to get it accomplished.
