Derivative of x x-8 2
WebBasically, you need to start over, and find the derivative of f (x) = x^u, where u is some function of x, and you will find d/dx (x^u) = x^u (ln (x) (du/dx) + u/x). So you find out, shockingly, that the 1 in the derivative was not really a 1! It was (exponent/base) which only becomes 1 when the exponent and base are both x! WebNov 20, 2011 · Well, the simple answer is if x < 0, it's obviously a linear line with a slope of -1, and when x > 0, it's a line with slope 1, and at x = 0, both formulas can be used and therefore we can't calculate the derivate. So: when x > 0, x ' = 1 when x < 0, x ' = -1 when x = 0, x ' is undefined

WebJun 21, 2024 · Recall the definition of the derivative as the limit of the slopes of secant lines near a point. f ′ (x) = lim h → 0f(x + h) − f(x) h. The derivative of a function at x = 0 is then. f ′ (0) = lim h → 0f(0 + h) − f(0) h = lim h → 0f(h) − f(0) h. If we are dealing with the absolute value function f(x) = x , then the above limit is. WebJul 28, 2015 · To do that, you need to write 2 as an exponential number that has the base equal to e. Use the fact that eln(a) = a to write eln2 = 2 This implies that 2x will be equivalent to 2x = (eln2)x = ex⋅ln2 Your derivative now looks like this d dx (ex⋅ln2) This is where the chain rule comes into play.
Weby=2^x log₂ y = log₂(2^x) log₂ y =x d(log₂ y) = dx dy/(y ln 2)= dx Rearrange to: dy/dx = y ln 2 since y=2^x dy/dx = (2^x )(ln 2) Although in this simple case there was not much to be gained by using the fact that f(x) = e^(ln (f(x)), there are problems where trying to solve the derivative any other way is nightmarishly difficult. WebSo let's do it that way, making sure to remember the chain rule: d d x x x 2 = 2 x log x ⋅ x x 2. Still, we know that neither of those answers can be right. So we'll just write them both down, and hope we get partial credit: d d x x x 2 = x x 2 + 1 + 2 x log x ⋅ x x 2. Share Cite Follow answered Oct 18, 2013 at 5:29 Slade 29.7k 1 34 81
