Hello, if anybody could help me with these problems I would greatlly appreciated it! If you could give me details to the solutions I would really appreciate it as well...

get the first, and second derivaties and graph the functions:

1) sin(e)^x

2) (2(e)^2x - 7e)/(5(e)^3x - 7(e)^2x + 5)

3) sec(ln(x))

4) (1/2)ln((1 + x)/(1 - x))

thank you again...
