Derivative of expression with two variables
WebApr 11, 2024 · In other words, the second derivative of X(x) is equal to the constant factor -k 2 times X(x) itself. It turns out that both sine and cosine functions have second derivatives that are scaled versions of themselves. Therefore, our solution to (Eq. 1) has the following form, where A and B are as of yet undetermined constants: X(x) = A cos(kx) + B ... WebThe derivative of 2 to the x is 2 x ln 2. We can write this as d/dx (2 x) = 2 x ln 2 (or) (2 x)' = 2 x ln 2. Since "ln" is nothing but natural logarithm (log with base 'e'), we can write this …
