check my ans please.... differentiate f(x)=arcsin(lnx)

OpenStudy (anonymous):

f'(x)=1/xsqrt(1+(lnx)^2)

OpenStudy (anonymous):

\[\left(\begin{matrix}1 \\x \sqrt{1+(lnx)^{2}}\end{matrix}\right)\]

OpenStudy (anonymous):

mistake here i believe

OpenStudy (anonymous):

should be 1 minus

OpenStudy (anonymous):

ohhh yes

OpenStudy (anonymous):

\[\frac{d}{dx} arcsin(x)=\frac{1}{\sqrt{1-x^2}}\]

OpenStudy (anonymous):

change the plus to a minus and you have it

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

:) yes
