Find out the general formula for the tangent vector and unit tangent vector to the curve specified by
r→ (t) = t2 i→ + 2 sin t j→ + 2 cos t k→.
Solution
First, by common formula we mean that we won't be plugging in a particular t and thus we will be finding out a formula that we can utilize at a later date if we would like to find the tangent at any point on the curve. Along with that said there really isn't all that much to do at this point other than to do the work.
Here below is the tangent vector to the curve.
r→′ (t) = 2t i→ + 2 cos t j→ - 2 sin t k→
To obtain the unit tangent vector we require the length of the tangent vector.
|| →r′ (t)|| = √ (4t2 + 4cos2 t + 4 sin2 t)
= √ (4t2 + 4)
After that the unit tangent vector is,
what is the product of the solutions to the equation: x2+4x=-4
let R be a (noncommutative) ring. Given that a,b and a+b ? R are all units, prove that a^(-1)+b^(-1) is a unit
If the area of a small size pizza is 78.5 in 2 , what size pizza box would required for the small pizza? (Note: Pizza boxes are calculated according to the length of one side.)
1. Suppose n ≡ 7 (mod 8). Show that n ≠ x 2 + y 2 + z 2 for any x, y, z ε Z. 2. Prove ∀n ε Z, that n is divisible by 9 if and only if the sum of its digits is divisible by 9.
Proof of Root Test Firstly note that we can suppose without loss of generality that the series will initiate at n = 1 as we've done for all our series test proofs. As well n
