I graduated from high school for four or five years! I basically forgot all the math knowledge in high school! But now I suddenly say I have to take an exam! There are still 20 days! Where should I learn from! Functions: trigonometric function, logarithmic function, exponential function, can draw pictures, do a series of problems according to images, 1 day can solve them.

Series: various questions of arithmetic and geometric series, 1 hour is enough.

Inequality: basic inequality, by the way, find a few small questions, 1 hour is enough.

Geometry: reading! Restore your imagination.

Then find the first eight fill-in-the-blank questions in the college entrance examination paper, because it contains other scattered knowledge points. Look at the answer. I don't know how to post it again. Let everyone help you. They are all masters of mathematics.
