$\begingroup$What's the integration of $$\int \sin^5 x \cos^2 x\,dx?$$ Julien44k3 gold badges83 silver badges163 bronze badges asked Feb 3, 2013 at 1949 $\endgroup$ 2 $\begingroup$ Hint Write $$ \sin^5x\cos^2x=\sin^2x^2\cos^2x\sinx. $$ Now use $\cos^2x+\sin^2x=1$ and do the appropriate change of variable. This is the general method to integrate functions of the type $$ \cos^nx\sin^mx $$ when one of the integers $n,m$ is odd. answered Feb 3, 2013 at 1954 JulienJulien44k3 gold badges83 silver badges163 bronze badges $\endgroup$ $\begingroup$ $$ \int \sin^5 x \cos^2x dx $$ $$= \int\sin^2x^2 \cos^2x \sinx dx$$ $$=-\int1 - \cos^2x^2 cos^2x -sinx dx $$ Let $u = \cosx$ $\implies du = -\sinx dx$ $$= -\int1 - u^2² u² du$$ $$= -\int1 - 2u^2 + u^4 u^2 du $$ $$= -\intu^2 - 2u^4+ u^6 du$$ $$= -\left\frac{u^3}{3} - \frac{2u^5}{5} + \frac{u^7}{7}\right + C$$ $$= -u^3\left\frac{1}{3} - \frac{2u^2}{5} +\frac{ u^4}{7}\right + C $$ $$= -\cos^3x \left\frac{1}{3} - \frac{2\cos^2x}{5} + \frac{\cos^4x}{7}\right + C $$ $$= -\cos^3x\frac{15\cos^4x - 42\cos^2x + 35}{105} + C $$ answered Oct 21, 2015 at 1432 $\endgroup$ 1 $\begingroup$ Using trig identities, you can show that $$\sin ^5x \cos ^2x=\frac{5 \sin x}{64}+\frac{1}{64} \sin 3 x-\frac{3}{64} \sin 5 x+\frac{1}{64} \sin 7 x$$ To do this, first use the "Power-reduction formulas" to reduce to get $$\sin^5x=\frac{10 \sin x - 5 \sin 3 x+ \sin 5 x}{16}$$ $$\cos^2x=\frac{1 + \cos 2 x}{2}$$ And then use $$\cos 2 x \sin nx = {{\sinn+2x - \sinn-2x} \over 2}$$ answered Feb 3, 2013 at 2000 gold badges81 silver badges139 bronze badges $\endgroup$ 5 You must log in to answer this question.

Theintegral of cos (x) is equal to sin (x). We can check this by differentiating sin (x), which does indeed give cos (x). Finally, as with all integration without limits, there must be a constant added, which I'll call c. So the final answer is. ∫ x sin (x) dx = -x cos (x) + sin (x) + c.

The answer is =-1/5cos^5x+2/3cos^3x-cosx+C Explanation We need sin^2x+cos^2x=1 The integral is intsin^5dx=int1-cos^2x^2sinxdx Perform the substitution u=cosx, =>, du=-sinxdx Therefore, intsin^5dx=-int1-u^2^2du =-int1-2u^2+u^4du =-intu^4du+2intu^2du-intdu =-u^5/5+2u^3/3-u =-1/5cos^5x+2/3cos^3x-cosx+C

The equation can be written as On separating the integrals As we know, dcos x = - sin x dx Therefore, put cos x = t and dt = - sin x dx in above
Integrale pangkat x cos x dx ∫ e^x sin x dx: This is a lovely example of integration by parts where the term you are trying to integrate will keep repeating and you end up going in circles. This example is to show how to solve such a problem. As usual you choose the simplest term for u hence u=ex, and therefore du/dx=ex.
