Cofunction Identities Worksheets
Cos, cot, and cosec are cofunctions of sin, tan and sec, hence they are prefixed with "co". Highlighted here is the relationship between the basic trig functions whose arguments together make complementary angles. Learn the cofunction identities in degrees as well as radians from the trigonometric identities chart and practice exercises like solving and evaluating trigonometric functions. These printable handouts are designed for high school students. Grab a few worksheets for free!
Incorporated here are tasks to determine the angle of a trigonometric function using the cofunction identities that make a sum of 90o or π/2 with the angle of its cofunction.
Tackle these two-part pdf worksheets featuring exercises to express a trigonometric function as an acute angle less than 45o or π/4 in Part A and greater than 45o or π/4 in Part B.
Specifically dealing with degrees, these printable worksheets encompass exercises to determine the value of 'x' by solving the trigonometric expression applying the cofunction identity.
