Integral of sin^4(x) Practice: Integration using trigonometric identities. sin2 x+cos2 x = 1 in one of three forms: cos2 x = 1−sin2 x sec2 x = 1+tan2 x tan2 x = sec2 x −1. If your function contains 1−x2, as in the example above, try x = sinu; if it contains 1+x2 try x = tanu; and if it contains x2 − 1, try x = secu. Sometimes you will need to try something a bit diﬀerent to handle constants other than one.

Átalakítás után az (5) szabályt alkalmazzuk: Z f( x) dx = 1 Integrarea este una dintre cele două operații de bază din analiza matematică.Nefiind evidentă și imediată, spre deosebire de diferențiale, tabelul cu integrale unor funcții cunoscute este foarte util. Funcțiile rezultate în urma integrării se numesc primitive.. Această pagină este o listă cu câteva dintre integralele unor funcții des întalnite; o listă mai detaliată se Po mojom prechádzajúcom článku som popisoval rozdiely medzi priemerom, modusom a mediánom. Bol som oslovený, aby som podobným spôsobom popísal integrály a derivácie. Ide o náročnejšiu látku, je to vyššia matematika, matematická analýza, takže je náročnejšia na pochopenie, vyžaduje si určité znalosti.

If you evaluate sqrt (8-8cosx) + c from 0 to 2pi, you'll get 0. but with the absolute value, you'll get the correct answer, 8. i got the same answer as van1011: 2sqrt(2-2cosx) (see above to post to see how), but to consider the absolute value, you take the integral from 0 to pi and multiply the answer by 2, giving 8.

That's actually pretty straightforward because sine of 0 is 0. 4 times 0 is 0, and sine of 2 times 0, that's also 0. So everything with the 0's work out nicely. And then what do we have here? Sine of pi over 2-- in my head, I think sine of 90 degrees; same thing --that is 1. And then sine of pi is 0, that's 180 degrees. So this whole thing
