## anonymous 4 years ago can sum1 explain the procedure of finding the integrals of 3/5y+4 , 3y/5y^2 +4 , 3/(5y^2 +4) and 3y/5y^2 +4 through integration by substitution

minor change-please help with this ones 3/5y+4 , 3y/5y^2 +4 , 3/(5y^2 +4)^2 and 3y/5y^2 +4

2. anonymous

see the first two are easy ....in the first one you have $\frac{3\ln(5y +4)}{5}$and the second one put denominator = t and substitute

3. anonymous

same with fourth but in third you need partial fraction
