So do this by a right triangle.
tan θ=tan arcsecx
θ=arcsecx
x=secθ
x=1/cosθ
cosθ=1/x
In a right triangle, this would look like the following
___________________________________e
________________________________s__o
____________________________u______p
_____hypotenuse=1________n_________p____opposite=[1-(1/x^2)]^(1/2)
____________________e______________o
________________t__________________s
____________o______________________i
________p__________________________t
____y__θ________________________e
h____a____d____j____a____c___e___n__t
adjacent=1/x
the tangent of theta is then the length of the opposite over the adjacent, so it is
{[1-(1/x^2)]^(1/2)}/(1/x)
This is going to simplify to
[(x^2)-1]^(1/2)
That's how you do it. Sorry about all the parentheses and lines in the triangle, but I don't know how to do it any other way.

What rule must be applied to inequalities when you divide or multiply by a negative number?
You have to flip the inequality sign. If it is less than(<) it has to become greater than(>). If it is greater than(>), it has to become less than(<). If it is less than equal to(<=), it has to become greater than equal to(>=). If it is greater than equal to(>=)., it must become less than equal to(<=).

What is the comparison operator used for not equal to in Excel?
You can use the Not function or the <> operator, which is the < and the > beside each other. To see if the values in A1 and A2 are not equal to each other, you can type: =A1<>A2 or =Not(A1=A2) In each case they will either give you TRUE if they are not equal or FALSE if they are equal, in the cell that you enter the formula into.
