Q. 1 Consider the parametric curve x = secΦ y = tanΦ ; Find dy/dx at Φ = π/3, without eliminating the parameter Φ.
I The region R is the region bounded by y = ln x, the x-axis, from x = 1 to x = e. (a)Set up the integral or integrals needed to find the area of R using partitions along the x-axis and then using partitions along the y-axis. (b)Using the method of disks or washers, set up the integral or integrals needed to find the volume when the region R is revolved about (i) the x axis (ii) the y-axis (iii) the line x = e. (c) Using the method of cylindrical shells, set up the integral or integrals needed to find the volume when the region R is revolved about (i) the x axis (ii) the y-axis (iii) the line x = e.
