How to make a table of variations?
The study of functions is carried out from secondary school.
The polynomial, exponential, logarithmic or trigonometric function with its variations and limits is studied.
We must find the extremes, the asymptotes and above all, draw this function .
To do this, it is necessary to learn to develop a table of variations through several stages:
- derive function
- factor it to express it in the form of a product or a quotient of expressions
- study f ‘(x) in the interval l
- elaborate the table of variations of f over l
- draw the function on its interval
When your math teacher teaches you the sign of a derivative function, it will be when you discover the tables of variations.
The math exercises done on a regular basis will make you more precise and will allow you to approach this concept of the subject with more rigor.
In fact, you always have to pay attention to correctly positioning the reference points on the curve to avoid mistakes.
Do not hesitate to help you with corrected exercises so that you do not encounter surprises on the day of the exam, and in this way, put all the opportunities on your side to succeed.
