This integral is mostly about clever rewriting of your functions. As a rule of thumb, if the power is even, we use the double angle formula. The double angle formula says sin^2theta=1/21-cos2theta If we split up our integral like this, int\ sin^2x*sin^2x\ dx We can use the double angle formula twice int\ 1/21-cos2x*1/21-cos2x\ dx Both parts are the same, so we can just put it as a square int\ 1/21-cos2x^2\ dx Expanding, we get int\ 1/41-2cos2x+cos^22x\ dx We can then use the other double angle formula cos^2theta=1/21+cos2theta to rewrite the last term as follows 1/4int\ 1-2cos2x+1/21+cos4x\ dx= =1/4int\ 1\ dx-int\ 2cos2x\ dx+1/2int\ 1+cos4x\ dx= =1/4x-int\ 2cos2x\ dx+1/2x+int\ cos4x\ dx I will call the left integral in the parenthesis Integral 1, and the right on Integral 2. Integral 1 int\ 2cos2x\ dx Looking at the integral, we have the derivative of the inside, 2 outside of the function, and this should immediately ring a bell that you should use u-substitution. If we let u=2x, the derivative becomes 2, so we divide through by 2 to integrate with respect to u int\ cancel2cosu/cancel2\ du int\ cosu\ du=sinu=sin2x Integral 2 int\ cos4x\ dx It's not as obvious here, but we can also use u-substitution here. We can let u=4x, and the derivative will be 4 1/4int\ cosu\ dx=1/4sinu=1/4sin4x Completing the original integral Now that we know Integral 1 and Integral 2, we can plug them back into our original expression to get the final answer 1/4x-sin2x+1/2x+1/4sin4x+C= =1/4x-sin2x+1/2x+1/8sin4x+C= =1/4x-1/4sin2x+1/8x+1/32sin4x+C= =3/8x-1/4sin2x+1/32sin4x+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

$\begingroup$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.
