Question

Differentiate arcsin(2x+1)

Answer 1

\[\frac{ 1 }{ \sqrt{1-(2x+1)^2} }(2)\]

Answer 2

@hartnn hey hartnn! can you check my work out?

Answer 3

\[\frac{ 2 }{ \sqrt{1-(4x^2+4x+1)} }\]

Answer 4

\[\frac{ 2 }{ \sqrt{-4x^2-4x} }\]

Answer 5

this is where im stuck, the book has it as

Answer 6

\[\frac{ 1 }{ \sqrt{-x^2-x} }\]

Answer 7

factor out 4 from denominator

Answer 8

correct

Answer 9

can you do that?

Answer 10

just pull out the four from the radical?

Answer 11

wouldnt that leave a 2 in the denominator next to the radical/?

Answer 12

yes,
\(\sqrt{-4x^2-4x}=\sqrt 4(\sqrt{-x^2-x})=2(\sqrt{-x^2-x})\)

Answer 13

u have 2 in numerator also!

Answer 14

OHHHHH!!!!!

Answer 15
