I'm not sure how to simplify it
Are you specifically instructed to use the given substitution? The substitution suggested by skeeter makes much more sense to use.
Yes I was given that as the instruction
Okay, look at what topsquark posted. Try factoring the radicand, and dividing out factors common to the numerator and denominator. What do you get?
im not sure this is right
How did you arrive at that result?
i factored out a 9 then it became 3.. and secant +1 became csc help me please
Factoring out the 9, which the square root makes it a 3 is good: However, . You are further instructed to write in terms of sines and cosines. How can you do this with the secant function?
secant= 1/ cosine
Where did the + 1 in the denominator come from?
my bad my mistake..
Also, I would use standard notation for the square of a trig function, i.e.: The way you have it written implies the argument (angle) is being squared. So, we now have: How can we rewrite the division as a multiplication?
