Trigonometric function avoids the hot spots in 20 12, and investigates the image and evaluation of the function through simple nature. 20 12 does not pay enough attention to the problems of functions and derivatives, but the source and teaching materials of combining series and linear programming are slightly higher than the teaching materials.
