Summer Blockbusters from a Nerdier Timeline

  1. Today one of my kids asked me this question:
    We were trying to simplify the expression
    sin(theta) / sin(90-theta) when a student just popped me with an answer: it is (theta) / (90-theta)

    When I tried to explain that we cannot just cancel out the sin, the big question came:
    WHY can’t we cancel that out?

    Can someone help me answer this :/? Because it seems no matter how I try to explain it, it doesnt exaclt make sense…

    1. Properly introduce (reintroduce) rational functions and discuss what f(x) / g(x) means.

      A really obvious one is if f(x) =1 …. f(2x)/f(x) clearly does not equal (2x)/(x)
