This is a special function that tells you relationship among inputs and outputs.

Cofunction identities examples math. Using a cofunction identity cofunction identities and how to determine cofunctions given a function value. Let s see how this can be applied. Tan π 3 a tan π 2 π 6 a tan π 2 π 6 a cot π 6 a cot π 3 a π 6. We discuss where these cofunction identities come from how.

Definition examples cofunctions. A function f is cofunction of a function g if f a g b when a and b are complementary angles. θ cotθ we have. You can use any one of them as formula in trigonometry problems.

You and the world famous but imaginary cosinius matham have decided to coauthor a thrilling high adventure. Sin a cos b if a b 90 sec a scs b if a b 90 tan a cot b if a b 90 the following figures give the cofunction identities. Scroll down the page for more examples and solutions on how to use cofunction identities. The following tables give some trigonometric identities.

What are cofunction identities. In math two angles are. The process remains the same whether you are in degree mode or radian mode. Scroll down the page for examples and solutions on how to use the trig identities.

The words coauthor and costar start with the prefix co. What are the co function identities. Cos 90 67 4 sin 67 5 cos 22 6 sin 67 5 therefore the value of cosine b is equal to sine a which is the cofunction and complement of b. A function f is cofunction of a function g if f a g b when a and b are complementary angles.

Sin a cos b a b cos 90 a sin a using substitution. Understand cofunction trig identities in this free math video tutorial by mario s math tutoring. There are six trigonometric ratios of complementary angle identities in trigonometry. Sin a cos 90 a cos a sin 90 a sin a cos b if a b 90 sec a csc 90 a csc a sec 90 a sec a csc b if a b 90.

Any function is called the cofunction if f a g b or a and b are the complementary angles. We often come across multiple functions in mathematics and one of the important methods is cofunction formulas in mathematics. The sine of complementary angle is equal to cosine of angle. Then from the trigonometric co function identity.
