Study of the sign of the first derivative
A detailed study of the sign of the first derivative is performed
Enter the expression of the Function WITHOUT entering y=
To enter the expressions you must use the app keyboard
Only certain functions appear on the keyboard by default. To display the keys related to the other functions, press the red keys (fn...for other functions).
By inserting the functions via the app keyboard, the names of the functions (eg sqrt () for the square root) will be inserted in the input box. Once the function has been entered, the cursor will be positioned within the round brackets (sqrt(|)) in order to write the function argument, e.g. √5 write sqrt (5).
The piecewise functions must be written according to the following example:
The following results are shown;
1) Domain of the function
2) The expression of the first derivative
3) The calculations to determine the sign of the derivative
4) The graph of the sign of the derivative with the deduction of the growth, decreasing and relative maxima and minima
Press the Calculate button to obtain the result
The details of the steps are shown only if the derivative is a polynomial or rational fractional function
