Whats the opposite of sin and cos?

Answer 1

secant/cosecant?

Answer 2

I'm not sure what you really mean by opposite in this case. Is this exactly the way the question was asked of you? If so, then you will remember that the opposite of 2 is -2 and the opposite of -6 is 6, etc. Then it must follow that the opposite of sin is -sin and the opposite of cos is -cos.

Answer 3

So there's either "inverse sine" and "inverse cosine" (which can most of the time be replaced with arcsin and arccos), which will get you from a number to an angle. (do the opposite of what sine and cosine do to the angle)

If you're talking about the inverse in the fractional sense (1/sin and 1/cos), then they would be cosecant and secant respectively:
csc=1/sin
sec=1/cos

Otherwise, if sin/cos, then sin/cos = tan, and cos/sin = cotangent or cot.

Answer 4

arcsin and arccos also called Sin^-1 and Cos^-1. They are inverses. Also another form of opposites is 1/sin=cosecant and 1/cos=secant.

Answer 5

If by "opposite" you mean inverse, then the inverse of sine is (1/sin) or cosecant and the inverse of cosine is (1/cos) or secant.

Answer 6

if sin and cos are differnt words the opposite of sin is Prayer and cos i dont know if there 1 word then sry cant help ya

Answer 7

the opposite of sin is cosecant and the opposite of cos is secant :)

Answer 8

Tangent. But the big question is why do you care in July? Shouldn't you be on a beach somewhere sucking up sunshine?

Answer 9

Do you mean sine and cosine? The answer is in your Trigonometry or geometry book.
By the way, Tangent is not the answer.

Answer 10

cos and sin.

Answer 11

Depends if you mean in combination or singularly. Either way you can view this help file in PDF.
