How is the value of sine and cosine of complementary angles relate?

The sine and cosine of complementary angles are related through the identity (\sin(90^\circ - \theta) = \cos(\theta)) and (\cos(90^\circ - \theta) = \sin(\theta)). This means that the sine of an angle is equal to the cosine of its complementary angle, and vice versa. Therefore, for any angle (\theta), the values of sine and cosine are essentially swapped when considering complementary angles.

What is the cosine function about?

The cosine function is mathematical equation to determine the adjacent angle of a triangle. The cosine of an angle is the ratio of the length of the hypotenuse: so called because it is the sine of the co-angle.

What is the relationship between the sine of an angle and cosine of the other acute angle in the same triangle?

In a right triangle, the sine of one acute angle is equal to the cosine of the other acute angle. This relationship arises from the definitions of sine and cosine: for an angle ( A ), ( \sin(A) ) is the ratio of the length of the opposite side to the hypotenuse, while ( \cos(B) ), where ( B ) is the other acute angle, is the ratio of the length of the adjacent side to the hypotenuse. Since the two angles are complementary (summing to 90 degrees), this relationship can be expressed as ( \sin(A) = \cos(90^\circ - A) ).


In a right triangle what is the ratio of the opposite side to the adjacent side?

The ratio is called the tangent of the angle. (also equal to sine/cosine)
