I just want to make sure im right. Find the derivative if y= arcsec(x+3).
I got
1
=======================
x+3sqrt(x+3)^(2)1
Is this the final answer or do you need to solve (x+3)^2 and get (x^(2) + 9x + 9)

The answer is
1

(x+3)sqrt[(x+3)^2 1]
Your answer should not have absolute value   symbols around x+3, and needs brackets around (x+3)^2 1, to show that you take the square root of everything in brackets.
