Well I tried...
Your processor couldn't take it lol
basically you know
how do you prove that the angle the ramp makes with the surface that is sits on is equal to the two angles that allow you to say
force of gravity x component is equal to mg sin theta
and that force of gravity y component is equal to mg cos theta
we you resolve the force of gravity into it's x components and y componetns you have two angles that make two traiangles
these two angles are equal to each other and also equal to angle the ramp makes with the surface that it sits on
how do I prove these angles are equal to each other???
I tried it's kind of hard wihout a picture tried to make one but your processor screwed it up lol let me know if you don't know what i'm talking about...
These boards do not allows diagrams because of the spacing problem. It allows one space but that's all. 15 spaces is just one space. 100 spaces is one space.
ok thanks
do you know the proof?
another attempt

test 15 spaces
test 100 spaces
If you want to do tables, this works fairly well.
number ....gender .....age
12......... male........14
13......... female......16
etc.
lol it didn't do anything
