WebThen recall that cos ( 2 x) = 1 − 2 sin 2 ( x) to give: 3 sin ( x) − 4 sin 3 ( x) = 1 − 2 sin 2 ( x) This is a cubic in sin ( x). For simplicity write y = sin ( x) to get: − 4 y 3 + 2 y 2 + 3 y − 1 = 0 − ( y − 1) ( 4 y 2 + 2 y − 1) = 0 So sin ( x) = 1 or sin ( x) = − 1 ± 5 4 So x = π 2 or x = π 10, 9 π 10, 13 π 10, 17 π 10 Share Cite Follow WebBy using the double-angle formula, you can solve sinx+cos2x=0 for x. The double-angle formula states that sin 2x = 2sin xcos x and cos 2x = cos2 x − sin2 x. Plugging these formulas in to the equation yields: 2sinxcosx + cos2 x − sin2 x = 0. canon pixma mp210 software free downloadWebYou can use this fact to help you keep straight that cosecant goes with sine and secant goes with cosine.

WebJan 24, 2013 · Math and Physics Tutor, with a math and physics degree. remember that sin2x + cos2x = 1, so cos2x = 1 - sin2x, and we can substitute that in place of cos2x ... sinx - sinx (1 - sin2x) = sin3x now distribute the sinx into the parentheses... You could also factor out sinx from the first two terms in the first line: WebFeb 1, 2024 · Replace in the equation sin 2x by using the identity: sin 2x = 2*sin x*cos x. cos x + 2*sin x*cos x = 2cos x* ( sin x + 1) = 0. Next, solve the 2 basic trig functions: cos x = 0, and (sin x + 1) = 0. Example 7. Solve: cos x + cos 2x + cos 3x = 0. (0 < x < 2Pi) Solution: Transform it to a product, using trig identities: cos 2x (2cos x + 1 ) = 0.
