How To: Use optimization methods in calculus

This video shows how to use optimization methods in calculus. Optimization means finding the maximum or minimum values of a quantity or finding when the maximum or minimum occurs.What quantities are optimized in economics?we want to minimize costs or maximize revenue.First steps in any optimization problem1.Identify the quantity to be optimized i.e., read the problem exactly what is exactly maximized or minimized.2.Identified the feasible domain. This is important because the math we can opti...

How To: Solve percent proportions

A percent problem is one in which you are given a quantity and asked to compute the value of a percent of it. You may also be given the whole quantity and a part of it and asked to compute the percentage of the part in the whole. To do these kind of problems you need to use the rule which states that the ratio of the part to the base it equal to the ratio of the percent to hundred. That is part/base = percent/100. This comes from the definition of percentage which states that percentage is eq...

How To: Find the percent change using proportions

In this video, the instructor shows how to identify the percentage change using proportions. When a given quantity increases or decreases by certain amount then we can calculate the percentage change in the quantity, which can be either increase or decrease based on the new value of the quantity. To solve these kind of situations you should know that the ratio of amount of increase (or decrease) of an amount to its original amount is equal to the ratio of percentage increase (or decrease) to ...

How To: Do exercises with resistance bands

The resistance band is great, because you can use it at home or even when you're traveling. This how-to video will show you what you need to do in order to put together a resistance band training program. This kind of workout will help you burn a lot of calories and fat! The first exercise is called "Squad Press": step on the resistance band with both of your feet, then drop down to a squad, onto the heels, the push up and lift the resistance band as high as possible. Watch this how-to instru...

How To: Measure current, voltage, resistance, and continuity using a multimeter

If you own or have access to an auto-ranging or manual-ranging multimeter you can measure several different aspects of circuits, resistors, and the like. For example, you can determine the resistance, voltage, continuity, and current with the multimeter to help you determine the precision of a resistor. This guide will help you learn how to use a multimeter to perform these tasks.

How To: Measure electrical resistance with a multimeter

This is a guided hands-on laboratory activity to help a student understand the proper and safe use of a multimeter to measure electrical resistance. These two video guides the student through the proper techniques for measuring resistance with a multimeter, but you'll need some assorted resistors, a rectifying diode, a photo cell, an electronic labs kit, and some other stuff.

How To: Make nitric acid

Watch this science video tutorial from Nurd Rage on how to make nitric acid. They show three ways to make nitric acid based on two different chemical approaches, both of which can be done using easily accessible materials.

How To: Fix common workout mistakes

There are some simple techniques to correct common workout mistakes. You should look for cues, which come in forms such as lack or form or lack of engagement. Elastic bands and be used in order to help direct someone into proper form. This will give them resistance and help them to see/feel the proper motion. You should be further pushing them in the incorrect motion with resistance. Adding a heavy chain or a weight to the lower back during pushup is also an example. Resistance may be used wi...

How To: Perform negative resistance training

In this tutorial, we learn how to perform negative resistance training with Jennifer DiDonato. Start of sitting down with your elbow resting on your knee and holding a weight of your preference. Now, lift the weight up by counting 1,2,3. Bring the weight back down by counting to 6, and keep doing this back and forth. This will give you a different work out since you are doing resistance on your way down as well as going up. Do three sets of this exercise on both sides, then try to do one more...

How To: Check whether quantities are equal in two lists in Microsoft Excel 2010

New to Microsoft Excel? Looking for a tip? How about a tip so mind-blowingly useful as to qualify as a magic trick? You're in luck. In this MS Excel tutorial from ExcelIsFun, the 724th installment in their series of digital spreadsheet magic tricks, you'll learn how to check if quantities are the same in two lists and show the differences if not, list the word "equal" if they are the same, and "not in list" if the lookup items is not in list using the MATCH, INSA, VLOOKUP and IF functions.

How To: Solve multi-step equations with absolute values

This educational math video describes the steps necessary to solve an equation involving absolute values. "Absolute value" refers to the magnitude of a quantity and is always expressed as a positive number. You can think of absolute value as the distance a number would be from zero if plotted on a number line. Positive 17 and negative 17 both have the same absolute value because both are 17 units from zero on a number line. Because of this, all absolute value problems have two answers, one wh...

How To: Make blue slime out of cornflour

This video loosely explains the method of how to make a blue colored slime from corn flour, blue food coloring, and a quantity of water which is undetermined. Quantities of ingredients to be added for this project vary and can be made up as the person goes along in combining the ingredients to produce the desired results. Ideally, the product should be of a slime like consistency, or can be described as 'gooey' in appearance. The resulting slime product should be easily stirred when it is sti...
