To find the tangent of an angle on the unit circle, simply find the sine and cosine values of the angle and then divide the sine value by the cosine value. That is, we can calculate the tangent of an angle, θ, by doing tan θ = sin θ / cos θRecommended...
cos 90° = 0, sin 90° = 1 and tan 90° is undefinedTry It Yourself!Play with the interactive Unit Circle below. See how different angles (in radians or degrees) affect sine, cosine and tangent:Can you find an angle where sine and cosine are equal?
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...

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....
Cosine Function in a Unit Circle: For an angle θ in a unit circle, the value of cos(θ) is equal to the x-coordinate of the endpoint of the angle. Similarly, the y-coordinate of the endpoint of the angle is equal to sin(θ). Answer and Explanation: In this...
解析 1 Graph θ = (π )2 in standard position on the same axes as a unit circle with center(0.0); its terminal ray intersects the circle at (0.1). The y-coordinate of the poin of intersection represents the sine value of θ = (π )2, so sin (π )2=1....
