Question
find the derivative of y with respect to the given independent variable.

1) y=7^(sec(theta))ln7
2) y=t^(1-e)

Answer
1.)
y = 7^(sec(theta)ln7)
y = (7^(sec(theta)ln7))(ln7)

This is probably wrong, since as you are learning something new i am as well, so i usually have to ask for help to give you some help. By looking up these types of problems, i have come along y' = (b^x)(lnb), also (b^(cx))' = c(ln(b)), but since this problem doesn't have an "x" in the value, i have to ask for help.

-------------------------------------------

2.)
y = t^(1 - e)
y' = (b^x)(lnb)
whereas "b" = t and "x" = (1 - e)
y' = (t^(1 - e))(ln(t))

I may get back to you, since this is my first time working with exponentials. So both of the problems you have given me are not 100% until i have gotten my answer back from someone else. Sorry i can be 100% certain, but i can't remember if i ever had to do derivatives of exponentials.
