why not use a calculator or a spreadsheet instead of a trig table?
what is the 150 coming from? are you doing something different than what you did at the starting?tan(45)=1
150*1=150
i dont understand this at all. i showed you the regular trig way to do this:tan(10) = .176327
150*.176327 = 26.44905
150-26.44905 = 123.551
am I even close?
so do like i said:Since the triangle on the launch side is 45 degrees then the base is h too. Then the base of the viewer's triangle is 150-h.Code: Select all
rocket path: l *. v a / | ` . i u / | ` . e n / |h ` . w c /45* | 10* ` . e h *---------*------------------* r |<===========150============>|
Code: Select all
triangle for A:
l A*. v
a / | ` . i
u / | ` . e
n / |h ` . w
c /45* | 10* ` . e
h *---------*------------------* r
| h | 150-h |
|<===========150============>|
so thats tan(10*)=h/(150-h)So do the tangent of the 10 degrees & make it equal to h/(150-h).
Of doing which?Is there a quicker way of doing this?
Certainly. It is useful to begin with the coded "picture" as provided by the other poster:Sorry, but, I could not understand the solution you tried to walk me through, would you mind posting something similar?
