Examples

1. Enter and name the expression, then use the diff command to compute the first and second derivatives of the expression.

           expr := x^n
           diff(expr, x)
           diff(expr,x$2)
         

   
2. Enter and name the expression, then use the diff command to compute the first and second derivatives of the expression.

           expr2 := x^(2*cos(x)) → / ln(x)
           diff(expr2, x)
           diff(expr2, x$2)
         

   
3. Use the context menu system to compute the first and second derivatives. Enter this expression.

               x^(2*cos(x)) → / ln(x)
             

   Right-click on the expression result, select differentiate, select x.

   Right-click on the first derivative result and select differentiate.

   

4. Select from the Expressions section of the left hand menu. Copy and paste to replace f with the expression you created in the previous example.
