NettetThe answer is that F ′ ( x) = 1 / x on R implies that there are constants C 1, C 2 ∈ R such that F ( x) = log ( x) + C 1 for all x > 0 and F ( x) = log ( − x) + C 2 for all x < 0. There is no such thing as "the integral of 1 / x ". – wj32 Feb 10, 2013 at 2:09 1 Nettet10. feb. 2015 · you could try expanding 1/ (1+x 2) as 1 - x 2 - … , and then integrating Nov 8, 2011 #14 kanika2217 3 0 there is a direct formula for these kind of questins i.e integrate [1/ (a^2+x^2)]dx = 1/a [arctan (x/a)] so u can assume a=1...so ur ans vil b (arctan x)...jst dis..

Nettet4. feb. 2024 · Evaluate the following integral : ∫1/(x{6(logx)^2+7logx+2})dx. asked May 22, 2024 in Indefinite Integral by Zafaa (30.4k points) indefinite integral; class-12; Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries. NettetSo 1 + x 2 = 1 2 ( t + 1 t). That was the whole point of the substitution, it is a rationalizing substitution that makes the square root simple. Also, d x = 1 2 ( 1 + 1 t 2) d t. Carry out the substitution. "Miraculously," our integral simplifies to ∫ d t t.

With the integration by parts given in previous answers, this gives the result. The distance around a unit circle traveled from the y axis for a distance on the x axis = arcsin ( x). arcsin ( z) = ∫ d s d x d x. Pythagoras gives the distance in terms of change in y and ... shop penny
