A log can be zero if the input (argument) to the log function is 1 (this is true for any valid base). We can see this easily by converting from log form to exponential form: 1. logB(N) = 0 2. B0= N This means N = 1, since any base raised to the power of zero is 1. See more The output of a log function (also known as the exponent) can be negative in certain cases. For example: 1. log2(0.5) = -1 We can confirm this by converting to exponential form to get: 1. 2-1= 1 / 2 = 0.5 However, the input … See more You cannot take the log of a negative number (unless you want to deal with complex numbers).

WebDec 4, 2015 · 1 Answer. Yes indeed. Derivative of velocity with respect to time is acceleration.That means if accelerations is zero, velocity must be constant. Now that constant could be anything like it could be 5 m/s .Also if the velocity is 0 (which is itself a constant) also indicates that acceleration is zero. Awesome! Web18 minutes ago · Teams.

WebPCA requires data with a mean of zero. Usually this is enforced by subtracting the mean as a first step. If the mean has already been subtracted that step is not required. However, there is no harm in performing the "subtract the mean" operation twice. Because the second time the mean will be zero, so nothing will change.
