Cos 2theta -sin theta interval 02pi
WebJan 14, 2015 · Start with θ = 0 you get r = 2 then move to θ = π 2 you will get r = 0 (then you have from here the upper half of the circle). From π 2 to π you have a negative r which don't have really much sense. Then you have to consider it from 3 π 2 to 2 π to complete the lower half. ∫ 0 π 2 1 2 ( 2 cos ( θ)) 2 d θ + ∫ 3 π 2 2 π 1 2 ( 2 ... Webcos(2x - pi/2) = -1 Solve for interval 0 less theta less 2pi

Webcos^2 x + sin^2 x = 1. sin x/cos x = tan x. You want to simplify an equation down so you can use one of the trig identities to simplify your answer even more. some other identities (you will learn later) include -. cos x/sin x = cot x. 1 + tan^2 x = sec^2 x. 1 + cot^2 x = csc^2 x. hope this helped! WebSo the object is rotating in the positive direction as t increases. If the object were rotating clockwise (negative angle), then the equations of TIME would read. x = 3 cos (-t), y = 2 sin (-t) And now as time moves forward, the object rotates clockwise (negative angle). This example can be a bit confusing because the parameter could be angle.
