what is dx dy equal to

what is dx dy equal to The difference between dy and dx is that dy is the derivative of x with respect to y while dx is the derivative of y with respect to x dy is calculated as dy y 2 2x 1 where y is the variable on the left side and x is on the right dx on the other hand is calculated as dx x 2 y 2

4 d dx 2x 3 Take the derivative of the expression 2x 3 with respect to x You will learn how to do this later If you are comparing this notation to other notation such as f pronounced f prime then dy dx would be the equivalent of dy means the linear change in y when we talk about derivative and it means with respect to y when we talk about integrals dy dx is another notation for derivative of y with respect to x so it is the same as y x In general we have a formula to remember df f x dx or dy y x dx

The symbol dy dx means the derivative of y with respect to x If y f x is a function of x then the symbol is defined as dy dx lim h 0f x h f x h and this is is again called the derivative of y or the derivative of f Df h f x h Often the notation df h is shortened to df or if y f x then we write dy instead of df Then the above definition is dy f x dx or dy dx f x Unless you are studying differential geometry in which dx is interpreted slightly differently dx is not the differential of a function

Here I introduce differentiation dy dx as used in calculus See the playlist on differentiation at youtube playlist list PL5pdglZEO3NjDXt9x If x is small then the second order term is negligible so that y is for practical purposes well approximated by dy f x x The differential is often useful to rewrite a differential equation

By definition of L x this difference is equal to f a dx In summary y f a dx f a L a dx f a f a dx dy nonumber Therefore we can use the differential dy f a dx to approximate the change in y if x increases from x a to x a dx We can see this in the following graph 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 dy dt 1 2 sqrt9 1 2 12 dy dt 1 2 1 3 12 dy dt 1 6 12 dy dt 2 Basically this is what is shown in the video but in a more direct format
