Jacobian How to use the chain rule? When you have a composition of functions (dw/ds, dw/dt)= (df/du, df/dv)(du/ds, dv/ds, du/dt, dv/dt) so it gives a vector Classify critical points 1. differentiate WRT each variable x and y. 2. set them equal to 0. then solve for the values (often take the equation that is easy to factorize and take its values. 3. replace the values obtained in the other partial equation set equal to 0 to get the points ***trick: you can add the equations some...

Without distinguishing row and column vectors, we can define vectors as follows: A special type of vector is the standard vector. However, in linear algebra, we sometimes need to distinguish row and column vectors, which are defined as follows: The two basic vector operations are addition and scalar multiplication. Using these two operations only, we can combine multiple vectors as in the following definition. Another concept that is closely related ...

scalar quantity that represents only magnitude, e.g., time, temperature, or volume. It is expressed using a single number, including any units. vector quantity that represents magnitude and direction. It is commonly used to represent displacement, velocity, acceleration, or force. Displacement (s) the distance and direction of a body's movement (an airplane flies east 100 nm). Velocity (V) the speed and direction of a body's motion, the rate of change of position (an a...
