The radius of the circle (length = 1 unit) represents the hypotenuse of the right triangle. So, the sides of the right triangle are 1, x, y.By the definition of the trigonometric ratios, we have$sin\; \theta = \frac{Opposite\; Side}{Hypotenuse} = \frac{y}{1}$ ...

A type of circle is the unit circle. Let us find out what do we mean by a unit circle? Definition: The meaning of unit, as we all know is 1. Therefore it can easily be made out that a unit circle is a circle with a radius of 1. The following figure represents the circle with ...
Unit Circle Definition The locus of a point which is at a distance of one unit from a fixed point is called a unit circle. Equation of a Unit Circle The general equation of a circle is (x - a)2 + (y - b)2 = r2, which represents a circle having the center (a, b) and the ...

The Definition of Tan With the Unit Circle The definition of tan given above is: tanθ=sinθcosθ But with the unit circle definitions of sin and cos, you can see this is equivalent to: tanθ=oppositeadjacent Or, thinking in terms of coordinates: ...
The definition of a function is satisfied. Moreover, when we draw the graph of y = sin x, we can imagine the unit circle rolled out in both directions onto the x-axis, and in that way marking the coördinates π, 2π, −π, −2π, and so on, on the x-axis....
