you can use t as an angle and think about it liek a polar graph
or you can use t as a 3rd dimension and graph it as a 3d plot whatever u like
Was this a correct approach, dan?
both are good
yes thats right
Alright, thanks! I was making sure of i'm getting the concept before going ahead and begin with the other problems.
if u want to think in polar also one more thing to note is that
you are starting with the tangent vectors along this circle then u have the perpendiculars along the circle
u just have a different sclaring factor on these vectors
I see. Does it also apply in 3d graphs?
it would be a slightly different interprataion if t wasnt seen as the angle
but r'(t) should still be perpendicular to r(t)
sint r(t) dot r'(t) = 0 no matter how u plot this
not all r(t) dot r'|(t) = 0 ofcourse though
so this would be a plane with that normal direction vector
its a line or a curve i mean not a plane
close its z=1+3(x/2)
its just that line along the plane y=-3
Lol that was a silly mistake I made
like that on that y=-3 plane we have this line existing
And this line would be z=1+(3/2)x
it looks flipped because x is positive when u go left on the planed noe
Thanks again :)
