integration
Are questions 16-18 and 28-33 related to integration by parts ??
I don't need solution but just wanna know the method cuz I hvnt done integration by parts

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.how did u try to solve it first ?
if u did not , try it with some basic stuff
if u did - click - some of them are simple substitutions, pretty sure they teach this type of integration in substitution, like substitute the expression in the root with u and solve ahead
I've tried substituting the terms , doesn't really seem to work out tho
Btw it's not all the questions, I've mentioned the range , the rest I've done
@hardcoreisdead you have to do some transformations in these integrals
like...?
Not necessarily, you can do it without ibp
For example, if you have a term (A) inside a square root and another term outside (say B), try to convert B so that it's equal or comparable to A
By comparable, I mean that the coefficient of the variable terms in B should be the same as in A
you can do this by multiplying and dividing by some number etc.
I'll try a few and get back to you
I tried and figured out a few
Still stuck in a few like 18th and 16th
For 16, multiply and divide by 7/3
For 18, convert x^2 into (1+x^2) - 1
bro how do u know that we mulitply by 7/3
Try to multiply and divide such that the coefficient of the variables match
could you pls share the steps for both ,i dont get it
18th is in terms of tan inverse btw
bro thats the property
didnt know the tan inverse thing
thanx

Comrade Rock Astley
This is easier to integrate
(Q 16)
Woahhh
Thanxx
we can also use the property of m(x+b) +t
then we compare the value and put it ang get the ans
we good?
Yeah its all clear
