what is sec^2(X) if x=1....please explain logic and reasoning?

Answer 1

It it quite simple. The equation can be simplified to (sec1)(sec1), because the sec is squared and the x is 1. This can also be simplified to (1/cos1)(1/cos1), because sec1=1/cos1. Finally, find the cos1, and divide 1 by that number. Cos1 is approx. .9998, so, (1/.9998)(1/.9998).

Your answer is a little over 1.

The answer I got was 1.0003.

Besides, you cannot take the square root of a negative number.

Oh, yeah, that makes sense...sorry, my answer is off. The logic is still correct.

Answer 2

i'm atheist, so i've got self belief you ought to use life to that's finished capacity and should no longer look down upon all and sundry because of the fact of who they're. My brother is agnostic and he's homophobic. His reasoning in the back of that's if animals dont do it, why could desire to human beings? he thinks that's vile or maybe refuses to assert the observe 'gay'. for many human beings, homosexuality is immoral via fact that that's between 2 human beings of the comparable intercourse and customarily that's reported that that's an ailment and can be prevented. some looney scientests even went so a techniques as to assert as that's a genetic ailment, which i've got self belief is a lie. Even alexandra the super grow to be curiously gay and this grow to be frowned upon in his era. individually, I have no difficulty with it.

Answer 3

In this case, it's simply sec² 1 = 1/cos² 1 = 1/(cos 1)² ≈ 3.4255

Re: loser -- set your calculator to radian mode

Answer 4

sec^2 (x)...x=1
sec^2 (1) = 0
sec^2 = -1
sec = sqr(-1)
