The textbook gave an example on how to do this type of problem, but the solution was way too complicated. I want to find a simpler way to solve it. So far, I found one solution by doing this. I know that sin equals -1 at the angle 3 pi/2. I solved for theta: 3 theta = 3 pi/2. I got pi/2. I know this is not Is there a similar formula relating sin^3(theta) to sin(3Xtheta) or cos(3Xtheta)? CalMeacham April 30, 2001, 5:54pm I have an assignment question that says "Express$\sin 4\theta$by formulae involving$\sin$and$\cos$and its powers." I'm told that$\sin 2\theta = 2 \sin\theta \cos\theta$but I don't know how this was found. #= cos^3 theta + 3i cos^2 theta sin theta - 3 cos theta sin^2 theta - i sin^3 theta# #= (cos^3 theta - 3 cos theta sin^2 theta) + i (3 cos^2 theta sin theta - sin^3 theta)# Then equating real and imaginary parts, we find: if x sin cube theta ycos cube theta sin theta cos theta andx sin theta y cos theta then a x cube y cube 1 b x square y square 1 c x square y square 1 - Mathematics - TopperLearning.com | mdptwjvv So, you think you’ve drafted a tweet, an email, a short story, or even a novel.
