# Is sin the X or Y?

**cos**θ, corresponds to the x coordinate is by definition; This fact is especially evident when using the special case of the

**unit circle**(r = 1) to express those definitions.

Also, is y sin over X?

The point of the unit circle is that it makes other parts of the mathematics easier and neater. For instance, in the unit circle, for any angle θ, the trig values for sine and cosine are clearly nothing more than **sin**(θ) = **y** and cos(θ) = **x**.

Secondly, what type of function is Y Sinx? -- and at all angles coterminal with them. The height of the curve at every point is the line value of the sine. In the language of **functions**, **y** = **sin x** is an odd **function**.

In respect to this, is Tan the X or Y?

The unit circle definition **is tan**(theta)=**y**/**x** or **tan**(theta)=sin(theta)/cos(theta). The **tangent** function is negative whenever sine or cosine, but not both, are negative: the second and fourth quadrants. **Tangent** is also equal to the slope of the terminal side. We talked about the sine and cosine functions.

Is Sin vertical or horizontal?

The **horizontal is sin** and the **vertical** cos because they have given the angle to the **vertical** in this question, not the angle to the **horizontal** as in the earlier examples.
