    Let dy/dx = secxtanx + ex.
    What is a general solution for y?
    y = tanx + ex 
    y = secx + ex + C
    y = tanx + ex + C
    y = secx + ex

    Solve the initial value problem explicitly:
    dy/dt = 1/(1+t2) + 2tln2
    if y = 3 when t = 0
    y = tan-1t + 2t
    y = tan-1t + 2t + C
    y = tan-1t + 2t + 2
    y = tan-1t + 2t + 3
