Functional overview: functional overview (overview)

Representative Courbet: Image (analytic function part)

Parite, imparite (functional attribute: parity (symmetrical with y axis); Singularity (symmetry with origin o)

Periodicite is periodic (there will be "repetition" on the image, such as π, 2π).

What is the Chinese name of sens de variation? It's just a table with+and-symbols on it to determine the direction of the image according to the value of y: bigger or smaller.
