Sketch the curve with the vector equation 7(t) = (t,2 – t, 2t). Indicate with an arrow the direction in which t increases.

Consider the trajectory r(t) =   t2+1t2-vt+1. Find a vector n per pendicular to the curve describe by this trajectory at time t = v. Hint: Sketch a schematic figure showing axes, the origin, the curve described by this trajectory, by the position vector r(t) at time t=v, and the vector n to be found.   Answer: n = <___,___>

Determine the equation for the line with normal vector n = [3,-4] passing through the point P(-1,-2)
