WebVector fields act on functions to give functions. Similarly, if you pick a cotangent vector at every point (in such a way that the vector varies smoothly), you get the notion of a differential ($1$-)form. Differential forms act on vector fields to give functions. WebTo determine where the vector field F is tangent to the curve C, we need to find where F is parallel to the tangent vector of C. (a).

WebTo determine where the vector field F is tangent to the curve C, we need to find where F is parallel to the tangent vector of C. (a). The curve C is given by y - 2x 2 = − 3. We can rewrite this as y = 2x 2 − 3. Taking the derivative of this with respect to x, we get dy/dx = 4x. So the tangent vector of C is 1, 4x .
