Question

If f(x,y,z)= (e^xyz)/((xyz)^1/2) then the partial derivative f1 (x,y,z) = ?

Answer 1

Need to be more clear. Yes at f(1) but partial derivative in relation to what?

Answer 2

sorry, f(1) is in relation to x

Answer 3

Find derivative of x, treat all variables like a constant, like it was 2 or 5 or something. Use quotient rule.

Answer 4

treat all other variables, y, z, ....
