WebLet g(x, y, z) = sin(xyz). (a) Compute the gradient Vg(1, 0, π/2). (b) Compute the directional derivative Dug(1, 0, π/2) where u = (1/√2,0, 1/√2). (c) Find all the directions u for which the directional derivative Dug(π, 0, π/2) is zero. (d) What are the directions u for which the above directional derivative reaches its maximum? and ... WebJun 30, 2016 · Explanation: in any number of ways. it is f (x) = (x − 1)−1. so you could use the basic definition, namely that d dx (xn) = nxn−1 . but here it is (x-1) and not x so we might wish to look at the chain rule and an intermediate substitution. we can say that. f (u) = 1 u where u(x) = x − 1. and then we can say from the chain rule that. irvine valley college beach volleyball

WebOct 23, 2024 · Derivative of 1/x 2 by Product Rule. Now, we will find the derivative of 1/x 2 by the substitution method together with the product rule of derivatives. For this let us put. z=1/x 2. We need to find dz/dx. This implies that. zx 2 =1. Differentiating with respect to x, we get that $\dfrac{d}{dx}(zx^2)=\dfrac{d}{dx}(1)$ WebJan 15, 2006 · f"(x) = -cos(x) 2nd derivative f"'(x) = sin(x) 3rd derivative f""(x) = cos(x) 4th derivative. and it would repeat after this right... see the pattern for a given n the nth derivative of cosine x can only be one of those 4 choices right. so if n/4 has a remainder of 1 the nth derivative is -sin(x) if n/4 has a remainder of 2 the nth derivative ...
