Copied or adapted from others: a highly derivative prose style \[dy=f'(x)\,dx\] 라는 익숙한 등식이 된다. In our case, we took the derivative of a function (f(x), which can be thought as the dependent variable, y), with respect to x. Example: y = sin −1 (x) Rewrite it in non-inverse mode: Example: x = sin (y) Differentiate this function with respect to x on both sides. dy/dx 라고 하는 것을 하나의 동류항처럼 인식하고 묶어서 정리해주면 dy/dx 를 구할 수 있겠죠. The second derivative is what you get when you differentiate the derivative. If you are comparing this notation to other notation, such as f' (pronounced f prime), then dy/dx would be the equivalent of f'(x), the derivative of f(x). Solve your math problems using our free math solver with step-by-step solutions. If that something is just an expression you can write d (expression)/dx. 2) If y = kx n, dy/dx = nkx n-1 (where k is a constant- in other words a number) Therefore to differentiate x to the power of something you bring the power down to in front of the x, and then reduce the power by one.
