Let dy/dx = secxtanx + e^x.
What is a general solution for y?

• y = tanx + e^x 
• y = secx + e^x + C
• y = tanx + e^x + C
• y = secx + e^x

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

• y = tan^-1t + 2^t
• y = tan^-1t + 2^t + C
• y = tan^-1t + 2^t + 2
• y = tan^-1t + 2^t + 3
