Function Plotter

Type a mathematical expression into the top line. The graph of the function of x will be plotted below. Note that scaling is 1:1.

The ploting of the curve does not require the equation to be parsed for each point. Instead, the parser "remembers" the structure of the expression and re-evaluates for different values of x. This causes a significant speed increase compared to parsing the expression for each point.

Try using constants (pi and e) and common functions (sin(x), cos(x), tan(x), asin(x)...) in your expressions to test the full functionality of the package.

Try the following sample expressions
(use cut and paste)

• 80 e^(-((x/40)^2))
• 20 ln(x/10)
• 10 tan(x/30)
• x^3 / 1e4
• 50 sin(x/20)
• 50 sin(x/10)*(sin(x/10) > 0)
