How do you find the directional derivative? To find the directional derivative in the direction of the vector (1,2), we need to find a unit vector in the direction of the vector (1,2). We simply divide by the magnitude of (1,2). u=(1,2)∥(1,2)∥=(1,2)√12+22=(1,2)√5=(1/√5,2/√5). What is directional derivative of a function? In mathematics, the directional derivative of […]

How do you calculate square feet cost? The equation to calculate this metric is: price per square foot = […]

Why is the Dirac equation important? It remains highly influential. It brought together two of the most important ideas in science: quantum mechanics, which describes the behaviour of tiny objects; and Einstein’s special theory of relativity, which describes the behaviour of fast-moving objects. How did Dirac predict the existence of the positron? Persuaded by Oppenheimer’s […]

How the Henderson Hasselbalch equation is derived? The following equation, which relates the pH of an aqueous solution of an acid to the acid dissociation constant of the acid, is known as the Henderson-Hasselbach equation. The Henderson-Hasselbach equation is derived from the definition of the acid dissociation constant as follows. How is the formula for […]
