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.
Does tangent of x equal cosine divided by sine?
No, it does not.
What is cosine squared theta equal to'?
Cosine squared theta = 1 + Sine squared theta
Do the equations sine plus cosine and sine squared plus cosine squared both equal 1?
No, they do not.
What does 1 - tangent squared equal?
pineapple
Can you make cosine squared X divided by2 equal to cosine squared x with some constant?
You could just pull out the half: it will be (1/2) cos squared x.

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 does cos squared x - Sin squared x equal?
2 x cosine squared x -1 which also equals cos (2x)
In a right triangle what is the ratio of the opposite side to the adjacent side?
The ratio is called the tangent of the angle. (also equal to sine/cosine)
Why is the tangent positive on quadrant III?
The tangent function is equal to the sine divided by the cosine. In quadrant III, both sin and cos are negative - and a negative divided by another negative is positive. Thus it follows that the tangent is positive in QIII.
What does the cotangent of infinity equal?
Cotangent of ∞ is not π/2. It's actually nonexistent since cotangent is the continually oscillating function.
