In the mathematical tasks you may be asked to input a value or function in GeoGebra.[br]The keyboard may not have the symbol you need, for example the square root symbol, or a power function. [br]A solution to this is using the ^ symbol followed by the argument. Try the examples below.[br][br]Examples:[br]1) [math]x^2[/math] = x^2[br]2) [math]e^x[/math] = e^x [br]3) [math]\sqrt[3]{\left(3x-1\right)}[/math] = [math]\left(3x-1\right)^{\frac{1}{3}}[/math] = (3x - 1)^(1/3)[br]4) [math]sin^2\left(x\right)[/math] = sin^2(x)[br]5) [math]cos^{2x}\left(5x\right)[/math] = cos^(2x)(5x)[br][br]Try inputting some of these in the box below and check you got the desired graph. Or you can try any other function!

Sometimes a slider will be provided. This slider enables you to adjust the value of a constant and visualise how the graph changes.[br][br]Other times you may be given a hint that will help you with the task, you should only access this hint[br]when you have attempted the task and are unable to proceed.[br] [br]Try the slider below, see what happens the function [math]f\left(x\right)=x^3+a[/math] when the constant [math]a[/math] is changed.[br]What do you observe?[br]Look at the hint when you are finished.
