OMG WE ONLY HAVE TO BLOG SIX MORE TIMES IN OUR LIVES!

Okay, so since i think we're going to be review trig for the rest of my life, i decided to go back to the beginning. We're going to review some reallllllly easy stuff!

We will be reviewing how to convert degrees into minutes and seconds, convert radians to degrees, and degrees to radians.

êThe first thing we’re going to learn is how to convert degrees into minutes and seconds.

1. The first thing you are going to do is take what is behind the decimal and multiply it by 60.
2. Next, to convert to seconds, you take what is behind the decimal in the minutes and multiply that by 60.

êêThe second thing we’re going to be learning is how to convert a degree into a radian.

1. Use the formula degree x π/180.

HINT: Type in the degree/180 into you’re calculator, put it into a fraction, and put Pibeside it.

êêêThe third and final thing we are going to be learning today is how to convert radians into degrees.

1. Use the formula Rads x 180/π=degree.

HINT: ∏ will cancel

Now, I am going to show you an example of each.

êExample 1: Convert 16.73º to minutes(‘) and seconds(“)

1. .73 x 60 = 43.8
2. .8 x 60 = 48

You’re answer would be 16º43’48”

êêExample 2: Convert 24º into Radians.

1. 24/180= 2/15 = 2π/15

You're answer would be 2π/15

êêêExample 3: Convert π/2 into degrees.

1. π/2 x 180/π =90º

You're answer would be 90º

YOUR WELCOME FOR THE COLORFULNESS!
