Chapter 9. Triangles, Trig and Trajectories: Going two-dimensional
So you can deal with one dimension. But what about real life? Real things don’t just go up or down - they go sideways too! But never fear - you’re about to gain a whole new bunch of trigonometry superpowers that’ll see you spotting right-angled triangles wherever you go and using them to reduce complicated-looking problems into simpler ones that you can already do.
Camelot - we have a problem!
The Head First castle is in imminent danger! Back when it was built, the longest ladder available from Sieges-R-Us was 15.0 m long. So the castle was designed with a moat 15.0 m wide and a wall 15.0 m high, making it impossible for anyone to put a ladder from the edge of the moat to the top of the wall.
But the Sieges-R-Us website has just been updated with a new top of the range 25.0 m ladder. It’s only a matter of time before someone comes to attack your castle armed with the new ladder, and your current defense system just isn’t big enough...
If you don’t act quickly, someone will turn up with the new ladder, and you’ll be toast. It’s ...
