Use the dropdown menu to select some sample functions, or type your own functions into the input box. The variable must be t. Your graph will be from 0 to n pi.[br][br]"t", "2", "ln(t)", "abs(t)", "a"[br]"a cos(t)", "a sin(t)", "sqrt(a^2 sin(2 t))", "sqrt(a^2 cos(2 t))", [br]"a + b sin(t)", "a + b cos(t)", "a sin(n t)", "a cos(n t)", [br]"3 + cos(8 t)", "1 + 3 cos(5 t)", "1 + 3 sin(t / 3)", "sqrt(t)",[br] "cbrt(t)", "sin(t) + cos(2t)", "sin(5t)+cos(10t) + 2"}

This applet can be used by teachers in a demonstration mode in the classroom or teachers can have students load it on their own computers with a worksheet to be complete for a grade.
