Question

2. For the angle β shown, assume that the circle has radius 1, sin(β) = a, and cos(β) = b. Evaluate the following in terms of either ± a or ± b.

(a) cos(180° + β)= _____

(b) sin(360° –β)= _____

This image depicts the unit circle, a fundamental concept in trigonometry. The circle is centered at the origin of a coordinate plane, with its radius labeled as 1. In this diagram: - A right triangle is inscribed in the circle. - The hypotenuse of the triangle, which is also the radius of the circle, is labeled as "1". - The vertical side of the triangle is labeled "a". - The horizontal side is labeled "b". - The angle at the origin is marked as β (beta). - The diagram includes a right angle marker at the intersection of sides "a" and "b", indicating that they form a right triangle. This representation is typically used to illustrate the trigonometric functions sine and cosine, with "a" corresponding to the sine of angle β, and "b" corresponding to the cosine of angle β, when considering the unit circle.
