DQ Topic 4.1 - Verify that the arc length integral equation properly measures the arc length of the unit half-circle asn. Use f(x) = v1 - x2 in the arc length equation over the domain -1 s x = 1. DQ Topic 4.2 - Verify that the surface area integral equation properly measures the surface area of the unit sphere as 4n. Use f(x) = \\1 - x2 in the surface area equation over the domain -1 s x s 1 DQ Topic 6.3 - Consider the parametric system = cos(t) and y = sin(t), 0 s t's 2n. This plots a counterclockwise circle of radius 1. What would you need to do to change this system to adjust the radius to 4? What would you need to do to change the orientation to clockwise? DQ Topic 7.1 - Consider the vectorv = a + 1, b + 1) , where a is the second to last digit of your student ID and b is the last digit of your student ID. Plot this vector in thery-plane. On the same plane, plot 2v, -1.5v, and
