i think his point is.. he wants a program for like TRIG LAWS... law of
cosines, sines.. a program with lots of built in equations.. like
geometry stuff.. area.. etc..etc...
heck i don't wanna do law of cosines.. and sines.. doing sins.. cos..
then storing the number then typing another crap on the home screen etc..
.. instead i like punching a program, pick SAS (side angle side) then
plugin the number and press enter and bam.. i get the answer nice and
quick..
and hehe.. i think you were THINKING TOO much for an answer.. (3
PARAGRAPHS???)
