To compute the unit circle with tangent values we just use the identity tan x = (sin x)/(cos x). Learn more about the unit circle with tangent by computing the table of values and learn how to graph the tangent function using the unit circle.
Unit Circle with Sin, Cos, and Tan We 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...
The Unit Circle is a circle with a radius of 1. Being so simple, it is a great way to learn and talk about lengths and angles.
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...

Calculate the coordinates for a point on the unit circle given the central angle in radians or degrees. You’ll also get the sine, cosine, and tangent in the results. Submit Feedback Solution: x = cos(θ) y = sin(θ) tan(θ) ...
Now we are ready to see the definitions of the trig functions using the trig unit circle. Consider the last example where we have a right triangle {eq}OPR, {/eq} with {eq}P(x, y) {/eq} being a point on the circumference and {eq}\alpha {/eq} being the angle depicted below. Im...
Using the trigonometric ratios in triangle OTP {eq}tan \theta =\frac{TP}{OP}=\frac{TP}{1} {/eq}, thus {eq}tan \theta =TP {/eq}. Figure 3 The tangent line drawn to unit circle can be used to find the tangent of any angle....
What is tan on the unit circle?Equation of a Circle:The equation of a circle is: {eq}(x - h)^2 + (y - k)^2 = r^2 {/eq} where: {eq}(h, k) {/eq} is the center of the circle r is radius of the circle When the center is {eq}(0, 0) {/eq}, then the ...
Define sine with the unit circle. What is the cosine of an angle in relation to trigonometry? Find each angle (in degrees) shown on the unit circle. Where on the unit circle is tan (sqrt(3) / 3)? What is the exact value of cos 45 degree as found on the unit circle?
