Using the quotient rule, the answer is d dx ( sin(x) x) = xcos(x) − sin(x) x2. While this is technically only true for x ≠ 0, an interesting thing about this example is that its discontinuity and lack of differentiability at x = 0 can be "removed". Let f (x) = sin(x) x. Use your calculator to graph this over some window near x = 0. how do i get the edge browser

WebFeb 4, 2024 · Here we will use the logarithmic derivatives. Step 1: Let u=e sin x. We need to find du/dx. Step 2: Taking logarithm on both sides, we get. log e u = log e e sin x. ⇒ log e u = sin x log e e. ⇒ log e u = sin x as we know that log a a=1. Step 3: Differentiating we get that. d d x ( log e u) = d d x ( sin x)
