Скачать или смотреть You CAN multiply by dx!

dy/dx is a ratio and you CAN multiply and divide by dy, dx and so on like a FRACTION!!! You don't belive me? Well, I can assure you that they are numbers and it's completely rigorous to treat them as a fraction (ratio). In this video we'll see how it can be done and the other ways in which that dy/dx symbol can be interpreted (at the end all identify the same object even though they aren't the same thing!). Like d/dx as an operator (or functional) that acts on some function or as a simple notation that just means the derivative with respect to the variable x!!!
