To enter a function you can use previously defined variables (e.g. numbers, points, vectors) as well as other functions.
- Function f:
f(x) = 3 x^3 – x^2
- Function g:
g(x) = tan(f(x))
- Nameless function:
sin(3 x) + tan(x)
f(x) = 3 x^3 – x^2. Then, you can type in
g(x) = cos(f' (x + 2))in order to get function g.
Furthermore, functions can be translated by a vector (see Translate Command) and a free function can be moved by using the Move Tool. Other Transformation Commands can be also applied to functions, but in most cases the result is not a function but a curve.
Limit Function to Interval
Function[x^2,3,5]both define a function x2 restricted to interval [3,5]
