Best Answer

Yes, except at odd multiples of pi/2 radians, where the cosine is zero so that the division is not defined.

No, it does not.


How does the tangent function relate to sine and cosine?

Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.

How is tangent defined?

The tangent of an angle theta is defined as sine(theta) divided by cosine(theta). Since the sine and cosine are Y and X on the unit circle, then tangent(theta) is Y divided by X. The tangent of a function at a point is the line going through that point which has slope equal to the first deriviative of the function at that point.


What is the relationship between the tan and cot?

Cotangent is 1 / tangent. Since tangent is sine / cosine, cotangent is cosine / sine.


How do you spell tangent?

That is the correct spelling of "tangent" (intersecting at one point, or sine divided by cosine, or opposite side over adjacent side).


1 minus 2 cosine squared divided by sine cosine is equal to tangent minus cotangent?

No, it is not. To be correct, the expression requires parenthesis, which are missing.
