Question

integrate 2/2x+3

Answer 1

take the two out so...

2 int (1/2x+3)

integral of that is ln (2x+3)/2

so 2 (ln 2x+3)/2

=ln 2x + 3

yes?

Answer 2

no that as to be ln 2x+3/2+C

Answer 3

i get the arbitrary constant...it was a minor mistake...but why is there an over two? when i take the derivative of ln (2x+3) it's exactly 2/(2x+3)

Answer 4

remember ur integrating...there is a rule that suffices that the integral of the 2x must be the denominator

wolframalpha agrees with me...the question is integral of 2/(2x+3) right?

Answer 6

well okay
