Derivative of f of x
WebDerivatives of the Sine and Cosine Functions. We begin our exploration of the derivative for the sine function by using the formula to make a reasonable guess at its derivative. Recall that for a function f ( x), f ′ ( x) = lim h → 0 f ( x + h) − f ( x) h. Consequently, for values of h very close to 0, f ′ ( x) ≈ f ( x + h) − f ( x) h. WebTherefore, to find the directional derivative of f (x, y) = 8 x 2 + y 3 16 at the point P = (3, 4) in the direction pointing to the origin, we need to compute the gradient at (3, 4) and then take the dot product with the unit vector pointing from (3, 4) to the origin.
