It explains how to find the angle of an equivalent cofunction....The 30-60-90 and 45-45-90 triangles are used to help remember trig functions of certain commonly used angles. For a 30-60-90 triangle, draw a right triangle whose other two angles are approximately 30 degrees and 60 degrees. The sides are 1, 2 and the square root of 3. The smallest side (1) is opposite the smallest angle (30 degrees).

The Six Basic Trigonometric Functions. Trigonometric functions allow us to use angle measures, in radians or degrees, to find the coordinates of a point on any circle—not only on a unit circle—or to find an angle given a point on a circle. They also define the relationship among the sides and angles of a triangle.

Co-function identities can be called as complementary angle identities and also called as trigonometric ratios of complementary angles. There are six trigonometric ratios of complementary angle identities in trigonometry. Remember, theta ( θ) and x represent angle of right triangle in degrees and radians respectively.These identities are called cofunction identities since they show a relationship between sine and cosine and a relationship between tangent and cotangent. The value of one function at an angle is equal to the value of the cofunction at the complement of the angle For example, sin(100) = cos(800) and tan — cot
