Integraldari e^x adalah angka itu sendiri. Integral dari e^ (nx) adalah 1/n * e^ (nx) + C; dengan demikian, integral dari e^ (4x) adalah 1/4 * e^ (4x) + C. Integral fungsi trigonometri harus dihafal. Anda harus mengingat seluruh integral berikut: Integral sin (x) adalah -cos (x) + C. (perhatikan tanda negatif!)

Integraltrigonometri adalah hasil kebalikan dari turunan trigonometri. Integral trigonometri bisa dituliskan sebagai rumus berikut ini : ∫ cos x dx = sin x + c. ∫ sin x dx = -cos x + c. ∫ sec 2 x dx = tan x + c. ∫ csc 2 x dx = cot x + c. ∫ sec x tan x dx = sec x + c. ∫ csc x cot x dx = -csc x + c.
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

Contoh1: Perhatikan sebuah integral berikut: Apabila kita melakukan substitusi u = ( x2 + 1), maka diperolehlah du = 2 x dx, maka sehingga x dx = ½ du. Lalu kita substitusikan ke dalam sebuah bentuk integralnya: Perlu diingat bahwa di pembahasan ini batas bawahnya yaitu: x = 0, diganti dengan u = 0 2 + 1 = 1, dan batas atas x = 2 diganti

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.

$\begingroup$ First off, not going to lie, this is for an assignment. Basically, we're given the integral $$\int \sin^5x\,dx$$ and rewritten form of $$\int [A \sinx + B \sin x \cos^2 x+C\sinx\cos^4x]\,dx$$ using certain trigonometric Identities. We're required to find the values of $A$, $B$ and $C$. Now for the life of me I can't find a set of transformations that will give me that transformation. The power reducing formula gets me to $$\int 5/8\sin X - 5/16\sin3X + 1/16\sin5X $$ and then I can use the multiple angles identity on $\sin3x$ and $\sin5x$, and then I use the power Identities again on the resultant and I just seem to keep going in circles, unable to get the transformation asked for and answer the question. Please send help! egreg235k18 gold badges137 silver badges316 bronze badges asked Sep 23, 2016 at 951 $\endgroup$ 0 $\begingroup$ This is easy. Notice that $$\sin^5 x = \sin x \sin^4 x = \sin x 1- \cos^2 x^2 = \sin x 1 - 2 \cos ^2 x + \cos^4 x ,$$ so $A = 1, \ B = -2, \ C = 1$. Integration, then, is easy, because $$\int \sin x \cos^n x \ \Bbb d x = - \int \cos x' \cos^n x \ \Bbb d x = \frac {\cos^{n+1} x} {n + 1} .$$ answered Sep 23, 2016 at 959 Alex gold badges47 silver badges87 bronze badges $\endgroup$ 2 $\begingroup$Hint You want to find values for $A,B$ and $C$ such that, for all $x$, we have that $$\sin^5x=A\sin x+B\sin x\cos^2x+C\sin x\cos^4x.$$ So try to plug there some specific values, such as $x=\tfrac\pi2$, to solve for $A,B$ and $C$. answered Sep 23, 2016 at 955 WorkaholicWorkaholic6,6332 gold badges22 silver badges57 bronze badges $\endgroup$ You must log in to answer this question.
