Find the equations of the normal plane and osculating plane of the helix r(t)=cos(t)i+sin(t)j+tk at the point P(0,1,pi/2)

Answer 1

@Zarkon

Answer 2

this is a textbook example but im confused on some things.

Answer 3

could you go look at my question while I take a look at yours oh and I am new and I do love gymnastics

Answer 4

wana tag me in your questions, and im not flexible enought to do gymnastics

Answer 5

so the solution in the book starts with: the normal plane at P has normal vector
r'(pi/2)=<-1,0,1>

Answer 6

Right, that is a correct normal vector, so now that you have a normal vector and a point that will lie on the plane, you should be able to write the equation for the plane

Answer 7

i have no idea what this means or how it relates

Answer 8

i know you get a normal vector through a cross product, but where did the r'(pi/2) come from

Answer 9

hi again i am actually very flexible

Answer 10

are you a boy or girl i cant really tell i am a girl

Answer 11

im a boy
