dy dt meaning This calculus video tutorial discusses the basic idea behind derivative notations such as dy dx d dx dy dt dx dt and d dy more
frac d dt is the differential operator It doesn t signify any particular value it s just meant to be applied to functions If you apply that operator to the function y y t then you get frac d dt y frac dy dt 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

Separable equations have dy dx or dy dt equal to some expression U substitution is when you see an expression within another think of the chain rule and also see the derivative For example 2x x 2 1 you can see x 2 1 as an expression within another 1 x and its derivative 2x The first and second derivatives of x Newton s notation Isaac Newton s notation for differentiation also called the dot notation fluxions or sometimes crudely the flyspeck notation 9 for differentiation places a dot over the dependent variable
In the video dy dt is defined as dy dx dx dt The chain rule for dy dx is defined as dy du du dx where u is the inner function of y Not sure if there is a gap in my understanding Now what s dy dx It s the limit as x 0 of y x x y x x So let s let x dx dt t and at the limit dy dt y x x y x t dy dx y x x y x x where only the denominator is different so dy dx dy dt t x

Dy dt The derivative of a function y with respect to time t It represents the rate of change of y with respect to t frac dy dt is equivalent to y t Likewise frac dx dt means the same thing as x t This notation is called Leibniz s notation because it was Leibniz who introduced it
1 Add x When x increases by x then y increases by y y y f x x 2 Subtract the Two Formulas 3 Rate of Change To work out how fast called the rate of change we divide by x y x f x x f x x 4 Reduce x close to 0 Dx is meant to represent a minute change in the variable x and similarly dy is a minute change in the variable y dy dx then is the minute change in y per minute change in x and is meant to be a ratio of the changes when y is a function of x
