[20分]請問first-order derivative 同埋second-order derivative有咩分別?

first-order derivative = dy/dx

Slope of the curve y=f(x).

second-order derivative = d^2y/dx^2

Slope of the curve dy/dx = slope of the curve (slope of y=f(x))

second derivative係將 first derivative再做多一次

second derivative係將 first derivative再做多一次 differentiation的步驟所得的結果
