You mix all the ingredients together, bake them, and then frost it!
Well, because if you do it out of order then you don't make what you are looking for!
Why can't we frost the cake, mix the ingredients, then bake it?
Just like how if you're trying to find the sin of something you must do opp/hyp, and for cos it equals adj/hyp, while tan is opp/adj.
However, if you do them out of order you could end up accidentally using the equation for sec, which is hyp/adj, or cot, which equals adj/opp, or even csc, which is hyp/opp! Then you'll have the wrong solution just by doing the steps out of order!
A big pile of MUSH!!
Hhhmmm? So what do we get if we make a cake out of order?
