To add a new 2D graph on KAlgebra, what you have to do is to go to the 2D Graph tab and click in the Add tab to add the new function. Then your focus will go to an input text box where you can type your function.
If you want to use a typical f(x) function it is not necessary to specify it, but if you want a f(y) or a polar function, you will have to add y-> and q-> as the bounded variables.
Examples:
sin(x)
x˛
y->sin(y)
q->3*sin(7*q)
q=0..100->q
If you have entered the function click on the button to display the graph in the main window.
