In mathematics, a derivative is a measure of how a function changes as its input changes. Loosely speaking, a derivative can be thought of as how much one quantity is changing in response to changes in some other quantity; for example, the derivative of the position of a moving object with respect to time is the object's velocity. The concept of a derivative developed as a way to measure the steepness of a curve; the concept was ultimately generalized and now "derivative" is often used to refer to the relationship between two variables, independent and dependent, and to various related notions, such as the differential.

feuds Clear. So when you're in here so we have two X plus. Why is equal to one? We're gonna find slow. I sleep. Why? Why equals negative two X plus one on our slope is negative too. And then we get why is equal to the square root of X refunding the equation of the tension line of the given curve which is equal to X to the 1/2 power. The derivative is equal to one over two square root of X. Then we're gonna find a normal line which is negative to square root of X. This is shown when we use negative one over the derivative. Then we do Negative two squared of X is equal to negative too. We're just gonna find for X and Y X equals one. And why is equal to half of one which is equal to one? Then we're going to find the equation. This is lye minus one is equal to negative too. X minus one. Why is equal to negative two x plus three
