#1/(3sqrt(11))#

Let #theta=sin^(-1)(0.1) Rightarrow sin(theta)=0.1=1/10=("Opposite")/("Hypotenuse")#

Let #("Opposite")=1# and #("Hypotenuse")=10#.

By Pythagorean Theorem,

#("Adjacent")=sqrt(10^2-1^2)=sqrt(99)=3sqrt(11)#

Hence,

#tan(sin^(-1)(0.1))=tan theta=("Opposite")/("Adjacent")=1/(3sqrt(11))#

I hope that this was clear.
