General design of one or two objective problem, a solution, accounting for about 12% of the score, i.e., about 18 minutes. Mostly, low-grade topic.In recent years the college entrance examination has been gradually abandoned the complex trigonometric transform and special skill examination, and focus on the image of trigonometric function and property test, the basic knowledge and basic skills test. In the test of trigonometry formula identical deformation at the same time, also directly examined the property of trigonometric function and image transformation, reduces to trigonometric function identical requirement, strengthen the trigonometric function character and image examination strength.
