Cos theta sin pi/2 - theta
WebWe must simplify (tan^2 theta - 1) <<<< note the 1 within this argument, we're taking an angle, and deducting 1 Start by simplifying the tan^2 theta angle tan^2 = sin^2+cos^2 = 1 << this we can agree on the solutions tell us to divide both sides by cos^2. so sin^2/cos^2 + cos^2/cos^2 = 1/cos^2 and 1/cos^2 is sec^2 << still following WebExpert Answer. Establish the identity sin [pi/2 - theta] = cos theta. Which of the following four statements establishes the identity? A. sin [pi/2 - theta] = sin pi/2 cos theta + cos pi/2 sin theta = (1) cos theta + (0) sin theta = cos theta B. sin [pi/2 - theta] = sin pi/2 sin theta - cos pi/2 cos theta = (0) sin theta - (1) cos theta = cos ...
