Nathan's week before Christmas blog

This is the first, I repeat first, of the three blogs that B-Rob demands that we do over the holidays.

In this blog, I will review chapter 7, because that was probably the easiest chapter we did all year.

The first thing that I will go over is converting degrees to radians and radians to degrees.

Convert 57 degrees to radians.
-All you do is multiply 57*π/180=57π/180; This reduces down to 19π/60

Convert 4π to degrees.
-All you do is multiply 4π*180/π=720 degrees.

Now I will go over how to get co-terminal angles.

Ex. Give a positive co-terminal angle for 55.
-Now you just add 360 to 55=415 degrees

Give a positive co-terminal angle for π/2.
-You can type this into your calculator by putting 1/2+2 and then convert it to a fraction.
You are adding 2π and the final answer is:
=5π/2

That is about it for this blog. Still got blog prompts to answer, so................
