[Para:]
You know -
Cosine it! Cosine i-i-it! Cosine it!
[ParaB:]
We can use this triangle right
Where hypotenuse is one...
An adjacent can be found
Once an angle measure's done. (Whoa.)
There's no need to have a right angle at all
Take any triangle since there's a law
Come on the formula you can recall. (So...)
[Chorus:]
When given side-side-side start with Pythagorus
Subtracting 2-a-b times cos C is enough
Come on you can assign it
Later inverse cosine it
Yes, you inverse cosine it (ay ay)
Or with side-angle-side, find the side you don't know
The contained angle, that makes this possible
Come on you can assign it
Oh, this time we cosine it
Surely you can cosine it
For angles we'll have to decide
How to start, so which is worst...
Best start with the largest
Obtuse then gets dealt with first. (Ohhhh)
(You see) There's no need to have a right angle at all
Take any triangle since there's a law
Come on the formula you can recall. (So...)
[Chorus:]
(Because) when given side-side-side start with Pythagorus
Subtracting 2-a-b times cos C is enough
Come on you can assign it
Later inverse cosine it
Yes, you inverse cosine it
Or with side-angle-side, find the side you don't know
The contained angle, that makes this possible
Come on you can assign it
Oh, this time we cosine it
Surely you can cosine it (Yeaaah!)
You know:
Cosine it! Cosine it! Cosine it! (ay ay ay)
Inverse:
Cosine it! Cosine it! Cosine it! (ay ay)
(Cause we know what to doooo)
'Cos we know what to do, we'll have vectors debut,
Well, after the inverse of a negative is known to be up in Quad 2
Because we know what we must do, we'll use dot product with flair
(Dot product with flair!)
Well, after the inverse of a negative is known to be up in Quad 2,
And obtuse!
(C'mon, you see...)
Subtracting 2-a-b times cos C is enough
Later inverse cosine it
[Chorus:]
When given side-side-side start with Pythagorus
Subtracting 2-a-b times cos C is enough
Come on you can assign it
Later inverse cosine it
Yes, you inverse cosine it (ay ay)
Or with side-angle-side, find the side you don't know
The contained angle, that makes this possible
(That makes this possible!)
Come on you can assign it
Oh, this time we cosine it!
You know!
