barney and the noobastank
i'm not a perfect student
there's many i'm told dat i didn't do
but i'll continue learning
remembering the sine and cosine rule
and so i have to say before i go
that i just want you to noe

take sin B over length B
will equals sin C over C
the reason why dis is true
and the reason's sin rule

i'm sorry dat i forgot u
it's sumthing i must live with everyday
to finf the length when you knew
sides B C and the angle A
you must use the cosine rule dat you fear
dat's y i need u to hear

you must take the square of B
and add to the square of C
deduct 2bc cosA
you will get the square of a!!
you will get the square of a!!
you will get the square of a!!
you will get the square of a!!
