How to use
Enter a function f (x) in the text input field marked "f(x)=".

 Example: f (x)=ex

Click the "Graph" button (this button also refreshes the graph).

Enter the derivatives f '(x), f ''(x), etc., in the text input fields marked "f '(x)=", "f ''(x)=", etc. (up to the fourth derivative).

 Example: f '(x)=f ''(x)=...=ex

Select a c value, the center point for the Taylor polynomials.

 Example: c=1

This can be done in either of two ways:

To erase the graph and all input fields, click the "Clear" button.
Examples
 Exponential: f (x) = ex, f '(x) = ex, f ''(x) = ex, f '''(x) = ex, f ''''(x) = ex; c = 1

 Trigonometric: f (x) = sin x, f '(x) = cos x, f ''(x) = -sin x, f '''(x) = -cos x, f ''''(x) = sin x; c = 0


Other Notes
The degree one Taylor polynomial (tangent line) will be shown in blue, degree two in red, degree three in green, and degree four in orange.
