(b) Write a vector equation for the plane that is perpendicular to the curve at t = 'if/4. (c) Find the length of the part of the curve that lies inside the sphere x2 + y2 + z2 = 17. Express your answer in the form of an integral. Hint: start by finding the points of intersection ,between the curve and the sphere. 4. Find the length of the loop of the curve x = 3t t 3 , Y = 3t2. 1...
