The Derivative of a function f ( x) denoted by f ′ ( x) is defined as the limit. f ′ ( x) = lim Δ x → 0 f ( x + Δ x) − f ( x) Δ x. So you limit is the derivative of the function f ( x) = 2 x. Geometrically, derivative of a … Nettet$\begingroup$ Your technique is bound to fail. The only thing you're using about sin(x) is that sin(x)/x) is less than or equal to 1/x, but 1/x blows up at x = 0 so this bound can't give you that the limit exists (let alone help you compute it). hemlock fruit
