1 mathematics, the new national college entrance examination curriculum standard, is the first of the big questions, namely 17 questions. 20 14 are you sure about trigonometric functions?
Just a few possibilities: trigonometric function, trigonometric solution, sequence, histogram. . . The national volume I looks simple, but there are many kinds of patterns. If there is no accident in our Hubei paper, the question 17 must be a triangle, but you can't guess how to test it. If you want to take the trigonometric function test, you will probably simplify the first question and substitute the second question into a triangle.
