Du Dx Math
The derivativeof with respect to is.
Du dx math. Example 1 find the derivative f x if f is given by f x 4 cos 5x 2 solution to example 1 let u 5x 2 and f u 4 cos u hence du dx 5 and df du 4 sin u we now use the chain rule. F u du dx dx f u du think about it. This video explains the difference between dy dx and d dx learn math tutorials bookstore http amzn to 1hdy8vm donate http bit ly 19ahmvx still need more. Du 2x dx is intuitively equivalent to writing du du dx dx since du dx 2x so the substitution rule which involves replacing du dx dx with du.
Calculus find du dx u 2x 5 9 differentiate both sides of the equation.
