Does anyone here take Mechanics 1?

me .

dun wrry imma finding professionals and bringig em here inshaAllah

the professional is here.. *le hoping he is right.. *

I think it'll be like this.. see attachment....

do u have any way to check if m right..?

Alright

Find the line of intersection of the two planes in vector form :
3x-6y-2z=3 , 2x+y-2z=2

-_____- I didn't u did..

1.use english.. -.-
2, it's self-explainatory.... ok, lemme try..
all u do is know that |z-c| = |z-b| makes a bisector b/w points b and c on the argand diagram(hat sketch)... notice, makes sense just like in vectors the magnitude of difference of z and c vectors gives u dist of z frm c and of z-b on rhs gives u dst on z frm b..... so when left pt is less than right it means z is closer to c than b.. so I shaded pts on the side near c (i.e. 0 in that legendary.. ahem.. sketch)....
anyway that's story of blue shade...
for green one.. all u do is go to pt u and make the 2 arguments there... half line of agr=0 and half line of arg = pi/4.. and its supposed to b between them.. shaded that with green....
the common area (shaded insanely) is what we were asked to provide...

now if some1 has trouble understanding.. they better ask their teacher to teach them complex loci properly.. -.-

tommz il do it insha Allah

 

[badrobot14]

wattay explanation...

is it a compliment or insult..? tel me so I can take my pointer off that ban user button.. xD

 

[Esme]

change ur dp n il help u xD

Why? What's wrong with it ?

 

[Esme]

tommz il do it insha Allah

Oh ok thanks and another one too
Line of intersection of these two planes :
x-2y+4z=2 , x+y-2z= 5

Thank you
