integral of 1 x 2 Start solving the integral x x2 1 dx d u x 2u x 1 2 du x u x 1 2 ln u x C 1 2 ln x2 1 C Because x2 1 0 then x2 1 x2 1 Therefore x x2 1 dx 1 2 ln x2 1 C
What is an iterated integral How do you evaluate the integral 1 sqrt 49 x 2 from 0 to 7sqrt 3 2 How do you integrate f x intsin e t dt between 4 to x 2 Apr 24 2015 This is an improper integral because the function is not defined at one of the limits of integration To attempt to evaluate the integral use the replacement 1 0 1 x2 dx lim a 0 1 a 1 x2 dx The is equals if the limit exists 1 0 1 x2 dx lim a 0 1 a 1 x2 dx ssssssssss lim a 0 1 x 1 a

Int 1 x 2 dx 1 x C Use the exponent rule a n 1 a n int x 2 dx Use the power rule of integration which states that int x ndx x n 1 n 1 C where n n 1 n in RR As Jim H mentioned it is worth noting that when faced with int 1 x dx the integral is ln x C x 1 C 1 x C Hopefully this helps The answer is 1 2arcsinx 1 2xsqrt 1 x 2 C Let x sintheta dx costhetad theta costheta sqrt 1 x 2 sin2theta 2sinthetacostheta 2xsqrt 1 x 2 Therefore the integral is I intsqrt 1 x 2 dx intcostheta costheta d theta intcos 2thetad theta cos2theta 2cos 2theta 1 cos 2theta 1 cos2theta 2 Therefore I 1 2int
Explanation I dx 1 x2 2 We will use the substitution x tan implying that dx sec2 d I sec2 d 1 tan2 2 Note that 1 tan2 sec2 I sec2 d sec4 d sec2 cos2 d Recall that cos2 2cos2 1 so cos2 1 2 cos2 1 2 I 1 2 cos2 d 1 2d 114271 views around the world You can reuse this answer

Explanation x2 x2 1 x2 1 1 x2 1 1 1 x2 1 1 1 x2 1 dx x 1 x2 1 dx in terms of the red bit use sub x tant dx sec2t dt this makes it 1 tan2t 1 sec2t dt 1 sec2t sec2t dt dt Through the Pythagorean theorem we see that the opposite side is sqrt x 2 a 2 So tantheta would be opposite over adjacent or sqrt x 2 a 2 a lnabs x a sqrt x 2 a 2 a C Note that a 1 a term can be factored from both of these which can then be removed from the logarithm as a constant log AB log A log B
