Homework Help: maths...

Posted by Aoi on Friday, June 19, 2009 at 9:19am.

Differentiate ln [x+√(x^2+1)] with respect to x

hence evaluate limit 0 to 1
∫ 1/√(x^2+1) dx

_________________________________________


Use the identity cos3x=4cos^3x-3cosx,
find ∫cos^3x dx
* Is there a printing error in the question? the limit is from pi/2 to pi/2?!
