Question

V(s,t)=sqrt(t)e^-s
what is the partial derivative of s

Answer 1

i tried (e^-s)(.5t^.5)
since -s is a constant then e^-s is a constant and then a constant times the derivative of sqrt(t)

Answer 2

-s isn't constant if you're taking partial in respects to it

Answer 3

omg! your right....the constant is t here...thx wow i am tired i guess

Answer 4

so would it be
sqrt(t)*-s*e^-s
?

Answer 5

\[\frac{\delta}{\delta s}[\sqrt{t}e^{-s}]=\sqrt{t}\frac{\delta}{\delta s}[e^{-s}]\]

Answer 6

and then (e^-s)*(.5t^-.5) is the partial derivative of t?

Answer 7

yes i believe it woudl be
