    1. By taking a derivative, verify that ∫secxdx=ln(secx+tanx)+C for −2π​<x<2π​.

      [4]

    Consider the differential equation

    xdxdy​=y+x2cos(xy​),0<x<2π​

    It is given that y=0 when x=1.

    1. Solve the differential equation using the substitution y=vx.

    1. Show that y=ex2∫f(x)dx is a solution to the differential equation dxdy​=2xy+ex2⋅f(x).

      [4]
    2. Hence solve the differential equation dxdy​=x(2y−x2ex2​) given that y=0 when x=−1.
