Question

differentiate y=1/x anyone show working pliz how to solve

Answer 1

With respect to x?

Answer 2

d/dx (x^n) = nx^(n-1)
y = 1/x = x^(-1)

dy/dx = -1 x^(-2) = - x^(-2) = -1/x^2

applying the power rule again,

d^2 y/dx^2 = -1 * (-2 x^(-3)) = 2 x^(-3) = 2 /x^3
so u can calculate as mch as u want

Answer 3

ok thanks
