Determine the dimensions of the box that will maximize the enclosed volume. Solution. We want to build a box whose base length is 6 times the base width and the box will enclose 20 in 3. The cost of the material of the sides is $3/in 2 and the cost of the top and bottom is $15/in 2. Determine the dimensions of the box that will minimize the cost.

In this section we give a general set of guidelines for determining which test to use in determining if an infinite series will converge or diverge. Note as well that there really isn’t one set of guidelines that will always work and so you always need to be flexible in following this set of guidelines. A summary of all the various tests, as well as …First, we need to recall just how spherical coordinates are defined. The following sketch shows the relationship between the Cartesian and spherical coordinate systems.

If the two functions f (x) f ( x) and g(x) g ( x) are differentiable ( i.e. the derivative exist) then the quotient is differentiable and, ( f g)′ = f ′g −f g′ g2 ( f g) ′ = f ′ g − f g ′ g 2. Note that the numerator of the quotient rule is very similar to the product rule so be careful to not mix the two up! The ... In order to use synthetic division we must be dividing a polynomial by a linear term in the form x−r x − r. If we aren’t then it won’t work.

We will also briefly look at how to modify the work for products of these trig functions for some quotients of trig functions.Nov 16, 2022 · W =F d W = F d. However, most forces are not constant and will depend upon where exactly the force is acting. So, let’s suppose that the force at any x x is given by F (x) F ( x). Then the work done by the force in moving an object from x = a x = a to x = b x = b is given by, W =∫ b a F (x) dx W = ∫ a b F ( x) d x.

The curvature measures how fast a curve is changing direction at a given point. There are several formulas for determining the curvature for a curve. The formal definition of curvature is, κ = ∥∥ ∥d →T ds ∥∥ ∥ κ = ‖ d T → d s ‖. where →T T → is the unit tangent and s s is the arc length.Section 6.4 : Euler Equations.

First, when doing a substitution remember that when the substitution is done all the x ’s in the integral (or whatever variable is being used for that particular integral) should all be substituted away. This includes the x in the dx. After the substitution only u ’s should be left in the integral.Nov 16, 2022 · In the section we introduce the concept of directional derivatives. With directional derivatives we can now ask how a function is changing if we allow all the independent variables to change rather than holding all but one constant as we had to do with partial derivatives.
