How to use inverse signs

Inverse signs on cosine, sine, and tangent look like this:

cos^-1, tan^-1, sin^-1

They are used to find the angle of a triangle, they can be found on your calculator by pressing the “2nd button” or the “shift” button.

How to label a triangle

A triangle has three sides, the hypotenuse, the opposite and the adjacent. To find these sides you would first look for the right angle, the right angle will point towards the longest side which is the hypotenuse. To find the opposite you would look for the other angle which would look something like 70°, this points towards the opposite side, and the last side, the adjacent side is found by labeling the last side which is not already labeled.

Finding a value

Example:

(x5)y = x50

you multiply the exponent 5 with whatever equals 50.

In this case y equals 10 because 5X10=50.

How to express the prime factorization of numbers

Step 1:

Divide number by least to greatest, trying factors such as 2,3,5,7,9 etc.

Step 2:

Continue dividing the number until you cant divide anymore

Step 3:

After dividing until you cant anymore turn the factors that you used to divide the number into an equation. Turn any two numbers in a row into a power.

Step 5:

The final product should look something like this.
