I am newbie. Can you show the example below to me, i wish to have step by step.
Question giving 4 points(cannot use any graft to support), which is (1,1), (2,3), (5,5),(8,6), then request to proof that (2,2) is in the area. How?
First step, we will get 4 line equations:
1. y=2x-1
2. y=0.6667x+1.6667
3. y=0.3333x+3.3333
4. y=0.7143x+0.2857
Second step?
y
10| A .______________. B
09| / /

07| E1. / E2. /
06| / /
05| / / E3.

02| / __ /. C
01| D./ __ -----

Please help me.
I need a formula or algorithm that can calculate whether each point E1, E2 or E3 is within the coverage area of 4 coordinates A, B, C & D like above. Result suppose is:
E1- Not
E2- Yes
E3- Not
Please help.
Thanks
