not a function of x?

ok, u is not a function of x, then i think you are gonna want to check the exponent of sec u

in case you get this, everything looks ok except the exponent on sec u. the n2 out front is good, the sec^(n3) times the sec u tan u (chain rule) is what is affecting the exponent

do you see what the exponent is now for sec u?

it's n3 no?

hsmt Group TitleBest ResponseYou've already chosen the best response.1
the n2 in front is correct. you also have product of secu^(n3) and then there is the chain rule that multiplies by secutanu. so, it is not n3

it would still be sec^(n2)

(n2)(secu)^(n3) times secutanu which equals (n2)(secu)^(n2) times tanu
