1. How to construct the graphic of function – s³n (x).
1) Work is conducted on the "Math function panel".
2) We press button  . To enter the field: sin(x). Than press button  . It's all.
2. How to find roots of the equation f (x) =0. For example cos(x^2) =0 on an interval [0; 5] with accuracy 0,0001.
1) Enter function–"cos(x^2)" or if that function is conducted it is chosen in the list of functions.
2) Choose the tab Roots.
3) In fields from, to it is entered 0 and 5 accordingly, in a field accuracy – -4.
4) Press button Calculate.
3. How to calculate determined integral. For example "-(x^2)-5x+1", on an interval [-6; 1] with accuracy 0,001.
