WebJun 3, 2024 · The limit definition of a derivative (using first principles) is such that. f'(x) = lim h->0 (f(x + h) - f(x))/h. Since f(x) = 2x 2 + 3x + 1, f(x + h) = 2(x + h) 2 + 3(x + h) + 1 = 2x 2 + 4xh + 2h 2 + 3x + 3h + 1.. Then, f(x + h) - f(x) = 2x 2 + 4xh + 2h 2 + 3x + 3h + 1 - 2x 2 - 3x - 1 = 2h 2 + 4xh + 3h. We can divide the entire expression by h so that WebDifferentiation From First Principles. We know that the gradient of the tangent to a curve with equation y = f(x) at x = a can be determine using the formula: Gradient at a point = lim h → 0f(a + h) − f(a) h. We can use this formula to determine an expression that describes the gradient of the graph (or the gradient of the tangent to the ...
