Uae 3d - geometrical concept....

usukidoll · Answer

I haven't even learned that. The professor didn't explain it too good.

experimentx · Answer

you are doing multivariable calculus?

usukidoll · Answer

no. but it involves the usage of this formula. 
|dw:1346513474551:dw|
where do I get the Point in this problem?

usukidoll · Answer

I don't know how to do that x(

experimentx · Answer

sorry ... passing through the point.

experimentx · Answer

take gradient of the plane ... that will give dc you normal.

usukidoll · Answer

gradient? is there a formula for that? or... is it based off of x+2y+2z=13?

experimentx · Answer

represent the line as 
(x-2)/1 = (y-3)/2 = (z-4)/3 = k

usukidoll · Answer

where did the 1, 2, and 3 come from?

experimentx · Answer

solve this equation with the plane x+2y+2z =13 to get x, y, z
