So the only solutions are x=pi, x=3pi/2. A much simpler way to find the answer is to observe graphically that the line x + y = -1 crosses the unit circle at (-1,0) and (0,-1) and therefore sin t + cos t = 1 1/ sinx(1 + cosx) = 1 + cosx + cos^2x 2/ sin^3x + cos^3x = sinx - cosx 3/ 3 cos^4x -4 sin^2xcos^2x + sin^4x = 0 Đăng chủ đề mới Cộng đồng học sinh Việt Nam - HOCMAI Forum Algebra -> Equations-> SOLUTION: Prove the identity ; (Cosx / 1 -sinx) - ( cosx / 1 +sinx) = 2tanx Log On Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.
