Question

differentiate the following trigonometric value

Answer 1

\[\sin \sqrt{x ^{2}+1}\]

Answer 2

ok if i understood right your question is
sin(sqrt(x^2+1))
then answer will be
cos(sqrt(x^2+1))*x/sqrt(x^2+1)

Answer 3

can u explain

Answer 4

that is by using chain rule of differentiation
its a bit difficult to explain...
first diffenrentiate the entire sin function then differentiate the square root then differentiate x^2 +1
