did ne one else prove q4 (b) [111] to be ab/2 instead of ab?
that's what i did but must have gotten some algebra wrong on the wayOriginally posted by Gruma
i used 1/2 x base x height
using base as acosx / 1 + sinx
and height as bcosx / 1 - sinx
what? i never heard of a formula for that!Originally posted by fitz33
the elegant way to do it was to use the formula for the area enclosed between three points..just apply the formula and thats it, only takes a few lines

a = 1/2 ab sin(@) or something, where a and b are two sides and @ is the angel between the sides
How do u know that @ is 90?Originally posted by nerdd
