Proof: The derivative of x^2 is x. x^2 = x * x = x + x ... + x (x times) Therefore, d/dx(x^2) = d/dx(x * x) = d/dx (x + x + ... + x (x times)) = d/dx(x) +

Proof: The derivative of x^2 is x.
x^2 = x * x = x + x ... + x (x times)
Therefore,
d/dx(x^2) =
d/dx(x * x) =
d/dx (x + x + ... + x (x times)) =
d/dx(x) + d/dx(x) + ... + d/dx(x) (x times) =
1 + 1 + ... + 1 (x times) =
x
