Sine Law Cos Law - Math Parody of Justin Beiber's baby

A song for my students. When do you use Sine Law? When do you use Cosine Law? Sing along and find out. To the tune of Justin Bieber's annoyingly catchy hit, "Baby".

Sorry if the vocals are a little shrill at times. I do not claim to have the best singing voice, and I also had a cold at the time of the recording.

Sine Law Cos Law ~ by Mrs. Caldwell (to the tune of "Baby" by Justin Beiber)

Know how to solve now, those right triangles
Just name the sides now, and choose a ratio
Pick from Sine, Cosine and Tangent
Then you just have to, have to deal with a proportion

But some triangles, just ain't right
And can't be solved, without a fight
Went to my teacher, said what can we do
There must be some way to solve these ones too

And she's like sine law, sine law, sine law ohhh
Use sine law, sine law, sine law whoahhhh
Use sine law, sine law, sine law ohhhhh
You can use the law of sines

Sine law, sine law, sine law ohhh
Use sine law, sine law, sine law whoahhhh
Use sine law, sine law, sine law ohhhhh
You can use the law of sines

For this you need an angle's value
And you need the side across from it too
Now set up ratios of sines to sides
You can solve anything, that a triangle brings
Now get the unknown side or sine
And rearrange to isolate on one side
I'm solvin' now, now, now, now
And I just can't believe that it's so easy going now that Iknow.

Sine law, sine law, sine law ohhh
Use sine law, sine law, sine law whoahhhh
Use sine law, sine law, sine law ohhhhh
You can use the law of sines

Sine law, sine law, sine law ohhh
Use sine law, sine law, sine law whoahhhh
Use sine law, sine law, sine law ohhhhh
You can use the law of sines

When I was solving, I hit a problem
I found two triangles that didn't have a value of an angle
And the side that it was across from
One had two sides, an angle in between
One had three sides, now just what does this mean.

Went back to my teacher
She said sine law won't do
You need the cosine law to solve this one for you
To get the square of the 'c' -- side, add the squares of 'a' and 'b' sides
Minus 2ab, times cosine of C, that's

Cos law, cos law, cos law Yeahhhhh
That's cos law, cos law cos law oooohhhhh
Use cos law, cos law, cos law Yeahhhh
Use the Law of the Cosines

Cos law, cos law, cos law Yeahhhhh
That's cos law, cos law cos law oooohhhhh
Use cos law, cos law, cos law Yeahhhh
Use the Law of the Cosines

Now I'm all done (4 times)

I'm all done.

great song mrs c, i cant seem to find ur lady gaga song, enjoyed class, i think everyone really enjoyed the potty one laughing and everything

[mrskcaldwell]

@pbilk1 I don't have a video for the Poker Face parody. You can listen to, and download if you like, the mp3 version on my homework page through the MDHS website.

[hapilton]

i have a test tomorow on this and i will be singing this in my head haha

awsome idea!

[mrskcaldwell]

@hapilton So how did you test go?

[CRCRmoshed]

nicely put together

i don't know what the kids are like in your school but if you where in my school you'd get ripped apart for this.

[mrskcaldwell]

@CRCRmoshed They thought it was funny. They did ask that I not choose a Justin Bieber song for my next math parody. So my next math parody was to the tune of "Friday" by Rebecca Black - which amused them even more.

[xMrsFamous]

this is so stupid.

[pbilk1]

@CRCRmoshed ripped apart in a good way or bad, if it was in a bad our school is good they wont do that to mrs. caldwell, we have a great school even if i just transfered here last year

[xoxtalihoxox]

I really like your idea of this but...I can't really hear you well do you mind putting the lyrics?

[hapilton]

@mrskcaldwell It went good! had to convince my perents that some of my time on youtube was actually useful haha
