This algebra 2 and precalculus video tutorial explains how to determine whether a function f is even, odd, or neither algebraically and using graphs. This video contains plenty of examples and practice problems using variables and constants. First, plug in -x into the equation and see if the sign changes. If all signs change, it's an odd function. If they all remain the same, then it's an even function. If some change while others do not, the function is neither even or odd. For graphs, even functions are symmetric about the y axis. For odd functions, the symmetry exists about the origin. For circles with even and odd properties, it does not pass the vertical line test and is therefore not a function.

Trigonometry is an easy way to work out the unknown sides and angles of a right angled triangle. The trick - know the side names - the opposite, hypotenuse, and adjacent, and know how and when to apply the trigonomic functions - sin, cos and tan. This is the only trick to getting it right every time!
In this lesson, students learn work out unknown side lengths using use sine, cosine, and tangent. You will need a scientific calculator for the problems in this lesson - and I'll show you how to access one on your computer.

What is Alzheimer's Disease and what causes it? In this video designed for elementary learning we explore those questions and help gain a deeper understanding of this disease. Many of us know someone who has been affected by dementia or Alzheimers and if not many of us might in the future. We hope this video helps students gain a better understanding of the disease, its causes, symptoms, and some prevention techniques.

Alzheimer's Disease is a type of dementia that causes problems with memory, thinking, and behavior. Dementia is a set of symptoms that may include memory loss and difficulties with thinking, problem-solving, or language. Alzheimer’s Disease is the most common cause of dementia.

Alzheimer's Symptoms: As a person ages, they may forget things. It is normal. However, one of the symptoms of AD is consistent memory loss, especially of recent events and new information. This is the most noticeable trait of Alzheimer’s, it usually occurs gradually at first, but gets worse over time.

Alzheimer's Prevention Ideas: As you learn, your brain is constantly making connections, and one way that might help prevent Alzheimer’s as you get older is to produce new connections. You can do this by staying active, mentally and physically. This also apples to adult family members or friends who do not have AD. Encourage them to be active too.

The solar system's most distant planet, Neptune, is a colossal world that still baffles scientists even today. Only one robotic spacecraft, called Voyager 2, has ever visited the planet, briefly allowing us to study its complex, dramatic atmosphere like never before. This is the only close-up footage ever captured of Neptune and reveals what it would be like to approach the ice giant planet towards the edge of the solar system.

Title: Dividing Fractions

You know that the multiplication of both whole numbers and fractions can be represented using an array that looks like this. This example shows four-fifths multiplied by two-thirds.
The product of multiplying the fractions is eight-fifteenths.
You also know that division is just another way of writing multiplication when one of the factors is unknown. That’s easy to see using this array. Let’s assume that you know the total size of the array, which is eight-fifteenths, and you know one of the factors in the multiplication, four-fifths.
But you don’t know the other factor, which we’ll now call X.
X is the number you need to multiply by four-fifths to get eight-fifteenths.
We can represent this situation with two different number sentences.
The first number sentence is written as multiplication. We know that four-fifths is multiplied by some number on this side called X.
And the result is eight-fifteenths.
We can also describe exactly the same situation with a division number sentence like this.
We know that we have eight-fifteenths, which is divided by four-fifths.
But we don’t know the length of this side of the array, which is the value for X.
So, these equations tell us exactly the same thing because they represent the same situation shown by the array.
The X in both equations represents the same number – it’s the missing value for the length of one side of the array.
While this array is helpful in seeing what a division problem represents, it’s not very helpful in finding out the number we need on this side, because we don’t know how many parts to divide each whole unit into. So how do we find this number? The best way is to use what we know about algebraic reasoning, using these two equations to describe the array.
We’ll start by finding the value of X in the multiplication equation.
This will help us later in understanding how to solve the division equation.
You know that you can multiply both sides of an equation by the same number and it doesn’t change the equation. We can use this to our advantage if we choose the right number to multiply by. We want a number that will give us one X instead of four-fifths X on the left side of the equation.
You know that multiplying any number by its reciprocal gives you 1. Let’s multiply fourth-fifths by its reciprocal like this.
Five-fourths times four-fifths is one, so the left side of the equation now becomes 1 times X, which we write as just X. You also know that if you multiply one side of an equation by a number you have to multiply the other side by the same number.
So, we multiply the right side of the equation by five-fourths.
When we multiply, we get forty-sixtieths.
We can divide both terms by 20, to see that X equals two thirds.
When we compare this to the multiplication problem we started with, we see that two-thirds is the correct answer, because two-thirds times fourth-fifths is indeed eight-fifteenths.
But how does this help us understand how to divide fractions? It’s actually very simple. Let’s look at these two statements from the equations.
Remember that X represents the same number in both equations. It’s the length of this line in the aray.
The equation on the right says you can find X by dividing eight-fifteenths by four-fifths. The eqution on the left says you can find X by multiplying eight-fifteenths by the reciprocal of four-fifths.
Using what you already know about algebra, you can prove that this same approach always works, but we won’t go through that proof here. It means that dividing any number by a fraction and multiplying that number by its reciprocal gives you the same result.
We’ll just look at a couple of examples to verify that this works.
We’ll start with this multiplication statement. Three-fourths times five-eighths equals fifteen-thirty-seconds.
