 SING-ALONG 10Math-Tans  present...."Solving for Unknowns"     (*aka "Into the Unknown", from "Frozen II")--------     Original by Kristen Anderson-Lopez and Robert Lopez; sung by Idina Menzel.     Parody Recorded (for play during Covid) : YouTube Here     Karaoke used from Kristen Ryan : YouTube Herexxxx, yyyy, zzzzI could fear you. But no way.Equation systems, cause no dismay.We have substitution, if we simply rearrange,Or a graph’s an option, and we shouldn’t find that strange, no.Whoa.There’s one more choice, elimination is its nameAnd if I scale up, which I might, we’ll still use it with planes.Row reduce our matrices, the form is echelonI’m sorry nth dimension, but your mystery is gone.We’ve found us an answer, this system’s been addressedWe have made a point of checking, now we’ll have no stress,Solving for unknownsSolve for the unknownsSolve all the unknowns(Ohhh. Ohhh.)What did we find? If no solution, don’t you shake,Do not fear double checking, maybe fixing some mistake.Yet inconsistent systems, they will have no point to spot.We might get cross, but independent they are not.Every way’s another outcome, as dependent systems grow,Since their set is infinite as we can show,Solving for unknownsSolve for the unknownsSolve all the unknowns(Ohhh)Sooooo,Rectangular?Parametric?May be polar?Make that graph quick!Ohhhhhh. (Ohhh.)Ohhhhhh. (Ohhh.)Whoa, x. Whoa, y. Whoa, z.Whooooa.What are your answers?No need to postpone,How did you follow through,Solving for unknowns!{Whew.}Previous XMas Specials: "Three Things of Math" ; "Sequenced" ;  "Triangles Rock" ; "Do We Have a Square Here?" ; "Like a Bell" ; "Polar Plot"; "O Factor Tree" ; "A Squared Song" ; "Decimal"TRACKBACK LINK FOR COMMENTS
