Might be, might not be. Depends on who the people are and where they are. Question is much, much to broad for a simple answer.
According to the Bible, the opposite of sin is righteousness.
It depends on your circumstances and what your faith/church says. In many churches it could certainly be said to lead to sin. Or in some churches it could be a sin even if you aren't in the same bed.
The opposite of moral is amoral. It means to be without morals.
Doing it, of course is not a sin, but your motivation for doing it could be, or not, it depends on the reason. Examples: To make yourself sexy and have the opposite sex lust after you? Sin. I am tired of this hair style and want to try something else? Not Sin. It all depends on your heart.
This word does not have an opposite.
Obviously the perspective of what is and is not a sin will depend on who you are talking to, as different Christians have diffenent views on sin and what the Bible commands. One Christian perspective would to say that having a certain sexual orientation is not a sin - but wrongly acting on that orientation - eg. to have sex outside of marriage or sex with a person of the same gender - would be.
The sides and angles of a triangle are generally described using a,b,c for the three sides and A for the angle opposite side a, B for the angle opposite side b and C for the angle opposite side c. Then use the Sine Rule provided that one of the given angles is opposite the given side. a/Sin A = b/Sin B = c/Sin C
Sin is the opposite over the hypotenuse.
the sine rule, angle (a) and opposite length is eaqual to angle (b) and opposite length. which are also equal to angle (c) and opposite length. Sin A = Sin B = Sin C ------- -------- ---------- a -------- b -------- c
Unsin.
