to solve such type problem, you have to use this method ,if both the functions are directly integrable ,then the first function is chosen in such a way that the derivative of the function thus obtained under integral sign is easily integrable . while doing this if you find this question in the form of the such function sinx/x, cosx/x ,1/logx , rootsinx , sin(x square ) exp.(x square) exp.(-x square) ,xtanx , and few more ..however these functions are differentiable but integration can not be found read less

firstly.....assuming 1+x=y, then integration by part e^y as 2nd function and 1/y as 1st ffunction

Respected tutors! I asked a question some time ago.My goal of asking question ,even after myself being a tutor, is to get clear with not so intuitive concepts, which i find intriguing. Q.What is the change in kinetic energy(ies) of body(ies) after collision of 2 moving bodies; you can take inelastic or elastic collision. 1- Remains same 2-Decreases 3-increases 4-any other possibilty All answers with 'decrease' options are correct, either elastic or inelastic collision. you can take any example and check. Q.Just think can KE be zero after collision? - this time its a bit more intuitive. Thanks.
it should remains same.. but if friction is taken into consideration then decreases would be the right option.
