? sec?x ?=? sec(x)
? (sec?x)2 ?=? (sec?x)(sec?x) ?=? sec2?x ?or? sec2(x)
? (sec?x)2 ?≠? sec(x2)
Hope that clears it up for you.
Have a good one
in that form it means ...sec x * sec x.....
sec^2 x = sec (x)^2 or sec (x*x)
Hope this helps
(sec x)2 = (secx)(secx) and is usaully written as sec2x
it is not the same as sec x2 !
Sec (Secant) is a Trig function. It is the Reciprocal of Cosine.
(sec x) ^2 == You take the secant of X then square it.
X would be an angle of a triangle.
wish people would use ^'s where they need to be, would make their attempts at answering much more clear
