\[\int\limits 1/(1+x ^{2})^{1/2}\] it will be \[\ln (1 + x ^{2})^{1/2}\]

you know that when the numerator is the derivative of the dominator then the integration is ln "dominator" :)

but the derivative of denominator should be there in the numerator

ok , the derivative of (x^2 )^1/2 is 1/2 (2x) so 2 cancel the other 2 :)

if the exponent is other than 1, we use power rule

yeah but we can't multiply it with 2x so ln(1+x²)½ is not the right answer

\[\ln (\sec \theta + \tan \theta) +C\]

by backward substitution \[\tan \theta =x\]
 2 years ago

AbdulRehmanBest ResponseYou've already chosen the best response.0
yeah that will give us integration of secθ that is ln(secθ+tanθ) and by substituting and we will get probably get ln(sec(tan^x)+x)
