Trigonometry can feel like quite an abstract subject. Arcane terms like "sin" and "cos" just don't seem to correspond to anything in reality, and it's hard to get a grasp on them as concepts. The unit circle helps substantially with this, offering a straightforward explanation of what the...

How do you find the tangent of a unit circle? If the tangent line at (1,0) to the circle is drawn, then the extension of the angle will intersect with the tangent line and a right triangle will be formed. Using this triangle, tangent values can be found. Sin/cos ratio would also ...

On the unit circle the functions take a particularly simple form. For example,sin θ = y1 = y.cos θ = x1 = x.The value of sin θ is the y-coördinate of the endpoint of the unit radius. The value of cos θ is the x-coördinate....
