WebNov 15, 2024 · Perfectly correct, if what you mean is ( f ( x 3)) ′. – Bernard. Nov 16, 2024 at 0:47. 1. do you want the derivative of f ( x 3) or f ′ ( x 3)? If its the first one then yes, you … WebExample: What is the derivative of x 2? For x 2 we use the Power Rule with n=2: ... Example: What is the derivative of x 3? f’(x 3) = 3x 3−1 = 3x 2 "The derivative of" can also be shown by d dx. Example: What is d dx (1/x) ? 1/x is also x −1. Using the Power Rule with n = −1: d dx x n = nx n−1. d dx x −1 = −1x −1−1 = −x −2 ... hifi fernseher test
How do you differentiate x^3+y^3=3xy? Socratic
Web10 years ago. Yes, you can use the power rule if there is a coefficient. In your example, 2x^3, you would just take down the 3, multiply it by the 2x^3, and make the degree of x one less. The derivative would be 6x^2. Also, you can use the power rule when you have more than one term. You just have to apply the rule to each term. Web2. If f (x) = e x 3 + 4 x, find f ′′ (x) and f ′′′ (x), 2 nd and 3 rd order derivatives of f (x). 3. Find the derivative of each of the following: (i) y = (5 x 7 + 3 x) (3 x 5 − 2 x 3 + 7) (ii) y = t + 5 − t 3 − 4 8 (iii) y = (tan x sin x ) 4 − sec (3 x + 5) (iv) y = (6 x + 7 ) csc (2 x) (2 + 4 x 2) 3 1 (v) y = (x + 2 x ) (4 ... WebSep 14, 2016 · Explanation: Begin by letting y = 3x. now take the ln of both sides. lny = ln3x ⇒ lny = xln3. differentiate implicitly with respect to x. ⇒ 1 y dy dx = ln3. ⇒ dy dx = yln3. … how far is amherst from boston
