Java YACAS

You need Java 1.5 or later to use this applet.


Please be patient while loading. Terminate Yacas by typing quit. Statements should end with a semicolon (;) and be case sensitive. Type Example(); to get random examples of Yacas calculations. Browse through previously entered expressions using the Up and Down arrow keys. Define variables and functions by using :=. Symbolic manipulation is the main application of Yacas.Yacas understand operators like + - / * and many (dozens of) commands where some are: Expand((1+x)^5); (expand the expression into a polynomial) Limit(x,0) Sin(x)/x; (calculate the limit of Sin(x)/x as x approaches zero) Newton(Sin(x),x,3,0.0001); (use Newton's method to find the value of x near 3 where Sin(x) equals zero, numerically, and stop if the result is closer than 0.0001 to the real result) DiagonalMatrix({a,b,c}); (create a matrix with the elements specified in the vector on the diagonal) Integrate(x,a,b) x*Sin(x); (integrate a function over variable x, from a to b) Factor(x^2-1); (factorize a polynomial) Simplify((x^2-1)/(x-1)); (simplification of expressions).
