In the case when we have enough linearly independent eigenvectors, we will not have to do anything special, but we will The eigenvalues and eigenvectors of a matrix are scalars and vectors such that.
Absolute Value Introduction The absolute value of a number is its value, or magnitude, without respect to sign.
It's the "amount" you are working with expressed as a positive number, ignoring any negative sign. Or, it's the number's distance from 0 on a number line. For example, the number 9 is 9 units away from 0. Therefore its absolute value is 9.
The number -9 is the same distance from zero, so its absolute value is also just 9. In both cases the magnitude, or absolute value, of your number is just plain old "9" because you've removed any negative sign that might have existed. Taking absolute value of a number leaves a positive unchanged, and makes a negative positive.
How do I write it? An absolute value is written like this: In certain places, such as calculator and computer programs, you may see it written as abs xwhich naturally means "the absolute value of x," but x is the common way your teacher probably wants you to write it on your homework and tests.
Applications Another use of the absolute value bars is actually to force a number to be negative, by writing - x. This takes the number, makes it positive, and then negates it. Why do we have to do it like that? Well, remember -- just putting a negative sign in front of a number doesn't always make it negative.
If the number was already negative then you just made it positive! Using the absolute value guarantees we have a positive value inside the bars, so the negative sign will definitely make it negative.Solve an absolute value equation using the following steps: Get the absolve value expression by itself.
