if an angle (other than the right angle) is the same, the third angle will also be the same. This is true because angles in a triangle add up to 180°. The hypotenuse, opposite and adjacent side ...

Start With a Right Triangle There are only two requirements ... It just happens that it's easy to show trig functions with a circle, but trig functions are really about right triangles.

These functions, such as the sine and cosine, are defined using right triangles. Imagine a right triangle with one side that lies flat against a table and another that shoots straight up from ...

As the numbers are known on the opposite and the hypotenuse, then we look for the ratio which uses both these sides (SOH CAH TOA). That ratio is the sine ratio. \(\sin (x^\circ ) = \frac{{opposite ...

The left and right sides of the brain control different functions in the body. Some people believe that the left and right sides of the brain can determine personality and behavior. However ...

Interestingly enough, the trigonometric functions that define those relationships are also closely tied to circles. Needless to say, this makes trig one of the hardest topics in math for students ...
