Math Problem Statement
[4 pts] State a formula using limits for the tangent vector to a parametrized curve at a point on the curve. Draw a sketch that explains this formula.
Solution
The sketch above illustrates the concept of a tangent vector to a parametrized curve. It shows the curve, points and , a secant vector between these points, and the tangent vector at , which represents the limiting direction as approaches zero.

Here are 5 related questions to expand your understanding:
- How is the tangent vector useful in describing the velocity of an object moving along a parametrized curve?
- Can you find the tangent vector for a given parametrized curve in a specific example, such as ?
- How does the concept of the unit tangent vector differ from the general tangent vector?
- What is the geometric meaning of the magnitude of the tangent vector?
- How would the tangent vector be affected if the curve is reparametrized?
Tip: The direction of the tangent vector provides crucial insight into how fast and in what direction a particle is moving along a curve at a given instant.
