WebJun 14, 2024 · We know that cos t is the x -coordinate of the corresponding point on the unit circle and sin t is the y -coordinate of the corresponding point on the unit circle. So: x = cos t = 1 2 y = sin t = √3 2. Try It 2.2.1. A certain angle t corresponds to a point on the unit circle at ( − √2 2, √2 2) as shown in Figure 2.2.5. WebThe problem asked to find the tan (15°) using angle addition identities. My approach was using tan (45°-30°) which led to the answer (3-√ (3))/ (3+√ (3)). The answer choice to the problem is (√ (3)-1) / (√ (3)+1) by using the approach tan (60°-45°). I plugged both answers into the calculator, both gave the exact same value of 0.267949192. philip stein watches australia

More Information WebInstead, think that the tangent of an angle in the unit circle is the slope. If you pick a point on the circle then the slope will be its y coordinate over its x coordinate, i.e. y/x. So at point (1, 0) at 0° then the tan = y/x = 0/1 = 0. At 45° or pi/4, we are at an x, y of (√2/2, √2/2) and y / x for those weird numbers is 1 so tan 45 ...
