Converting Radians and Degrees.

In the past two weeks, I caught on to a few new math formulas. The two that

I totaly understand, are the formulas for turning Radians into Degrees and turning Degrees

into Radians. Everybody relates circles to degrees; an entire circle is 360 degrees, 3/4 of a

circle is 270 degrees, half of a cirlce is 180 degrees, and 1/4 of a circle is 90 degrees. Well in

math, there are always multiple ways to read and work problems. Just as you can measure

a road by meters or inches, you can measure angles by Radians and Degrees.

Here are the names for the radians and degrees of a circle.

CIRCLE DEGREES RADIANS

4/4 360 2 pi

3/4 270 3 pi/2

2/4 180 pi

1/4 90 2/pi

Now, the formula to convert degrees to radians is:

Degree (pi / 180)

The formula to convert radians to degrees is:

Radians (180 / pi)

~~~~~~Here are some examples to help you get an idea of whats going on!~~~~~~

~~~( * will be used as degree sign)~~~

Example #1 Convert 200* into radians

~ plug 200* into the formula

~ 200*(pi/180)

~ work

~ 200/180 pi radians or 3.49 radians

Example #2 Convert 1.4 radians into degrees

~plug 1.4 into the formula

~1.4 (180/pi)

~work

~80.2*

Hopefully this will help anybody that would be in need for these formulas.
