WebJan 11, 2016 · Explanation: First, note that. bx = eln(bx) = exlnb. This allows us to differentiate the function using the chain rule: d dx [exlnb] = exlnb ⋅ d dx [xlnb] Just like d … WebThe complex conjugate is found by reflecting across the real axis. In mathematics, the complex conjugate of a complex number is the number with an equal real part and an imaginary part equal in magnitude but …

WebTake the derivative of both sides (note that we are taking dy/dt, not dy/dx, because we are taking the derivative in terms of t as the question calls for): dy/dt = (1/2 x^ (-1/2)) (12) where (1/2 x^ (-1/2)) is dy/dx and 12 is, as given, dx/dt. When dy/dx is multiplied with dx/dt, we get dy/dt. Since we are finding dy/dx when x is 9, we get: WebThe instantaneous rate of change of the height of the skydiver at any point in time is represented by the derivative of the height function. h(t) = 2200 – 4.9t 2. h'(t) = 0 – 4.9 (2t) … WebAug 23, 2024 · Taking the time derivative of the phasor $\vec{\mathbf{B}}$, $$\frac{\partial\vec{\mathbf{B}}}{\partial t} = j\omega Ae^{j\omega t}e^{-\phi} = j\omega \vec{\mathbf{B}}.$$ Share.
