We have 9^2 = 81 and 10^2 = 100;
So, 81 < 87 < 100;
9^2 < 87 < ( 9 + 1 )^2;
9 < < 10;
Finally, is irrational.
Well, by definition, the tangent vector is the vector that is the result of differentiating every component of the function. Hence, the tangent vector is T=(3,-5sint,5cost). This has a magnitude of
which yields |r|=
(by using the known trigonometric formula
that holds for all t). Thus, the unit tangent vector t is given by: t=
. Now, to find a normal unit vector, we just need to find a normal vector N and scale it appropriately. To find a normal unit vector, we can just find vector that satisfies V*T=0 (dot product of vectors). By inspection, we see that the vector N=(0, cost, sint) satisfies this requirement and that it is also a unit vector (due to the aforementioned trigonometric identity). Hence, a normal unit vector to our vector function is N.
