(It's not homework.) It is probably the fact that we are dealing with trig ratios cubed that is throwing me off. A question with squared trig ratios usually gives me no troubles. I keep running into a mess.

Dec 18, 2014 The triple angle identity of cos ⁡ 3 θ \cos 3 \theta cos 3 θ can be proved in a very similar manner. From these formulas, we also have the following identities for sin ⁡ 3 (θ) \sin^3(\theta) sin 3 (θ) and cos ⁡ 3 (θ) \cos^3 (\theta) cos 3 (θ) in terms of lower powers: Apr 30, 2001 The integral of secant cubed is a frequent and challenging indefinite integral of elementary calculus: ∫ ⁡ = (⁡ ⁡ + ⁡ | ⁡ + ⁡ |) +. There are a number of reasons why this particular antiderivative is worthy of special attention: The technique used for reducing integrals of higher odd powers of secant to lower ones is fully present in this, the simplest case.

### sin^3(x) = sin^2(x)*sin(x)=(1-cos^2(x))(sin(x)) Now set u = cos(x), du = -sin(x) So the integrand becomes -(1-u^2)du, which is easy to integrate. It becomes (1/3)u^3 -u + C. Plug in cos(x) for u after integrating, and there's your answer, which is

Their usual abbreviations are sin(θ), cos(θ) and tan(θ), respectively, where θ denotes the angle. The parentheses around the argument of the functions are often omitted, e.g., sin θ and cos θ, if an interpretation is unambiguously possible.

My Work so far: (27*(cos 279 + isin279)^1/3= 27^1/3 * (cos 279 + i sin 279) ^ 1/3 27 ^ 1/3 = cube root 27 = 3 3*(cos 279 + i sin 279) ^1/3= 3(cos 279/3 + i sin 279/3)= 3(cos 93 + i sin 93) Is my answer right? ===== Your answer is right, but it's only 1 of the cube roots. Find an the complex cube roots of w = 125 (cos 210 degree + i sin 210 degree). Write the roots in polar form with theta in degrees. z_0 = (cos degree + i sin degree) z_1 = (cos degree + i sin degree) z_2 = (cos degree + i sin degree) The antiderivative of involves sin^3 and sin, which can both be antidifferentiated, with the new antiderivative involving and cos.

Published: 28 June 2019 Last Updated: 18 July 2019 sin 3 ( I preferred this one on the grounds that, not only was the derivation simple, but that the numerical evaluation of the integral was also easy, mainly because it contains only one variable, sin(θ), which is zero at the origin and for integer multiples of π - unlike cos(θ).
