I have used both books. To be honest, I think the golden edition of mathematics is basically useless to people with poor foundation. The above questions are suitable for improving training. The summary in the gold edition of the college entrance examination is good, but it is really bad. Just memorize the above summary and practice the above questions. I have done several questions before, and I have taken similar tests later. But I think it's better to study the college entrance examination papers over the years. You don't have to do it, just look at his thoughts, and then you will have an idea next time you see this question. You must also listen in class, because the senior three teachers will review from the beginning and don't know if they can make up.

Formulas of trigonometric functions is the most important, and there are some small conclusions. Let's do a few more questions. In fact, the routine of trigonometric function is similar. Just practice a little more.

I used to be like you. Freshman basically didn't learn triangles and didn't even know the formula. It's all senior three, starting from scratch. Just to sum up the questions, mathematics in the college entrance examination is the second in our class. In fact, there are many regular things in the college entrance examination paper. It is good for you to study more. Don't be afraid. Start with the simplest.
