6 1 point If the terminal arm of angle A, in standard position, passes through point (-b, 2b), where b > 0, then the exact values of sin A, cos A and tan A are respectively: 2 15 15 , and - 2 O 2 and 2 V5 2 1 and 2 V5' V5 O 1 2 and - 2 V5' V5 7 1 point If the graph of y = sinx is compared with the graph of y = 3sinx, it will be found that: O both the x-intercepts and y-intercept change neither the x-intercepts or y-intercept are different the x-intercepts are different, but the y-intercept is the same O the y-intercept is different, but the x-intercepts are the same 8 1 point Which of the following equations represents a graph that has a period of > and an amplitude of 2? O y= 2sin(6x) y = 2csc(6x) y = 2 csc _x O y = 2 sin x
