Unit Circle with Sin, Cos, and TanWe just learnt that coordinates of any point on the unit circle are equal to $(cos\; \theta,\; sin\; \theta )$.Thus, $x = cos\; \theta$ and $y = sin\; \theta$Using these values, we can further calculate $tan\; \theta = \frac{sin\; ...

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 ...
Find exact values of the trigonometric functions secant, cosecant, tangent, and cotangentTo define the remaining functions, we will once again draw a unit circle with a point (x,y)(x,y) corresponding to an angle of tt, as shown in Figure 1. As with the sine and cosine, we can use...

The unit circle is visualized and explained with calculation steps, diagrams and animations. Enter the radian or the angle α to calculate the results. Negative values, decimals, fractions and π are supported. The solution is displayed step by step. All calculations are saved in the history. ...
Given the angle (in radians), we want to find the location this occurs on the unit circle. As a reminder, the unit circle begins at an angle of 0 on the far right, going counter-clockwise straight up we reach π/2, continuing counter-clockwise to the far lef...
