WebThe value of tan pi/3 can be calculated by constructing an angle of π/3 radians with the x-axis, and then finding the coordinates of the corresponding point (0.5, 0.866) on the unit circle. The value of tan pi/3 is equal to the y-coordinate (0.866) divided by the x-coordinate (0.5). ∴ tan pi/3 = √3 or 1.7321. 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° is 1.

Knowing that tan is negative in quadrants 2 and 4. the answer is in either of those two quadrants. BUT!!! since inverse of tan is restricted to quadrants 1 and 4 we are left with the only answer -pi/4.

WebTo find sin (36°) we can use the double angle formula sin (2𝑥) = 2 sin (𝑥) cos (𝑥) ⇒ sin (36°) = 2 sin (18°) cos (18°) = 2 (√5 − 1)∕4⋅√ (10 + 2√5)∕4 = (√5 − 1)√ (10 + 2√5)∕8. Again, squaring both sides allows us to get a neater result: sin² (36°) = (6 − 2√5) (10 + 2√5)∕64, simplifying to (10 − 2√5)∕16. 36° lies in the first quadrant, so
