Co-functionsThe Unit CircleRemember

Aim: Use complementary angles in order to find equivalent co-functions. cofunctionsFunctions that complement eachother:

sine = cosine(90 )ex: sin 30 = cos _____

tangent = cotangent(90 )ex: tan 45 = cot _____

secant = cosecant( )

ex: sec = csc _____

90 - 3090 - 45

Aim: Use complementary angles in order to find equivalent co-functions.

Try thEsE1. cos 10 = sin _____802. csc = sec___

3. sin (90 - )= ________cos 4. tan 50 = _____ 40cot5. Solve for x: sin (3x + 5) = cos (4x + 1)(3x + 5)+ (4x + 1)7x + 6 = 90x = 12Aim: Use complementary angles in order to find equivalent co-functions. = 90
