This example is to show how to solve such a problem. As usual you choose the simplest term for u hence u=e x, and therefore du/dx=e x..

Med partiell integration ges en möjlighet att integrera (bestämma primitiv funktion ) till vissa produkter av funktioner som annars är mycket svåra att integrera. trigonometriska funktionerna f(x) = sin kx och f(x) = cos kx, och funktionen f(x) Vi kan integrera funktionstermer var och en för sig istället för tillsammans, och To support my channel, you can visit the following linksT-shirt: https://teespring.com/derivatives-for-youPatreon: https://www.patreon.com/blackpenredpenTha Free Pre-Algebra, Algebra, Trigonometry, Calculus, Geometry, Statistics and Chemistry calculators step-by-step This calculus video tutorial explains how to find the integral of sin^3x using the pythagorean identities of trigonometry and integration by u-substitution. Integrating the third power of \sin (x) (or any odd power, for that matter), is an easy task (unlike ∫ \sin^2 (x)\,dx, which requires a little trick). All you have to do is write the expression as \sin (x)⋅ (\text {even power of }\sin), rewrite the even power using the formula \sin^2 (x) = 1-\cos^2 (x) , and apply the substitution u = \cos (x) (i.e. du = -\sin (x)dx ). What is the integral of sin^3x ?

This example is to show how to solve such a problem. As usual you choose the simplest term for u hence u=e x, and therefore du/dx=e x.. You choose sin x to be dv/dx, and therefore v = -cos x, which you can easily find using Array-valued function flag, specified as the comma-separated pair consisting of 'ArrayValued' and a numeric or logical 1 (true) or 0 (false).Set this flag to true or 1 to indicate that fun is a function that accepts a scalar input and returns a vector, matrix, or N-D array output.. The default value of false indicates that fun is a function that accepts a vector input and returns a vector output. sin(3x+2)dx= 1 3 cos(3x+2)+ C: OBS: R cos(x2)dx6= 1 2x sin(x2)+C,tyinrederivatanmåstearav konstant.
