Hey thanks buddy. can you brief me of how to do integration using ln, removing ctts etc... i have trouble in these... plz.

 

[AhShun]

For lnx
dy/dx = lnx
= (1)(lnx)
= dv/dx x U
then integrate by parts

what do you mean by ''ctts etc...'' ?

 

[Amy Bloom]

For lnx
dy/dx = lnx
= (1)(lnx)
= dv/dx x U
then integrate by parts

what do you mean by ''ctts etc...'' ?

For example a question like 3/2x-1 integrate this wrt x.

 

[AhShun]

dy/dx = 3/ 2x-1

y = 3/2 ln(2x-1) + C

 

[Amy Bloom]

dy/dx = 3/ 2x-1

y = 3/2 ln(2x-1) + C

Can you give me explanation of how you came to that?

Guys, especially since 2day is the last day of revision for Math P3, stop discussing here, and discuss everything of this thread:
