福建上学期高三数学期末考试（Fujian last semester, third grade math final exam） Bad is against, but the bad guys are few people, not unworthy, not in order to prevent a few bad friends out. More importantly, in order to prevent the bad suspicion, calculating others, will make oneself become the Regal isolationist, and neither friends, also lost business partners, finally only a defeat. Fujian Normal University attached the third grade mathematics final examination last semester Volume 1 (multiple-choice question) A total of 60 points Reference formula: Integral and difference formula of trigonometric functions Sin alpha, cos, beta =[sin (alpha + beta), +sin (alpha beta)] Cos sin =[sin (alpha beta alpha + beta) Sin (alpha beta)] Cos alpha cos, beta =[cos (alpha + beta), +cos (alpha beta)] Sin alpha sin beta =[cos (alpha + beta) Cos (alpha beta)] The area of the side is truncated cone frustum and formula: Among them, C/ and C respectively indicate the perimeter of the upper and lower surfaces Said ofbending or long bus Volume formula of a ball: Where R represents the radius of the ball A choice: this question is 12 a. Every day 5 A total of 60 points For each question there are four options. There is only one option that meets the requirements of the subject 1. if the square of a complex is equal to 2I Then the plural modulus is () A.1 B.2 C.0 D. 2. known f (x) G (x) is defined as a function on R The set M={x|f (x) = 0} N={x|g (x) = 0} that The set {x|f (x) - G (x) = 0} (equal) A.M N B.M N C. D.M, a 3. set the function y=f (x) image as shown Then the analytic expression of F (x) is () A.y=|x|1 B.y=|x1| C.y=|x|+1 D.y=|x+1| 4. proposition a: established Is the proposition B: established A. sufficient and non essential condition B. necessary non sufficient condition C. sufficient and necessary condition D. is neither sufficient nor necessary 5. the coordinate of a point on the curve represented by the equation x=cos theta (theta as parameter) is () Y=cos2 theta A.
