This problem has two independent parts. a) (1 point) Find an equation for the line r(t) that passes through Po(1,1,0) and P(1,-1,1). What is the curvature of F at t = 20227 F(t)= (- Curvature (2022)= b) (1 point) A curve has description r(t) = (e, sin(e), 0). What is the torsion magnitude [7] of the curve at t=2022? Hint: Which plane does the curve lie on? |(2022)|
