Cofunction identities calculator
While it is possible to use a calculator to find \theta , using identities works very well too. First you should factor out the negative from the argument. Next you should note that cosine is even and apply the odd-even identity to discard the negative in the argument. Lastly recognize the cofunction identity.1)Use the cofunction identities to evaluate the expression without the aid of a calculator. sin2 21° + sin2 69° = 2) Apply the appropriate fundamental trigonometric identity and simplify. cos2 80° + sin2 80° = 3)Use the cofunction identities to evaluate the expression without the aid of a calculator. cos2 (48°) + cos2 (42°) =.For instance, we can observe that 75 = 30 + 45 (we say why we chose these numbers further down). We use this decomposition to apply the angle addition formula, so we input it into the sum and difference …

Use the cofunction identities to evaluate the expression without using a calculator. cos^2 20 degrees + cos^2 52 degrees + cos^2 38 degrees + cos^2 70 degrees;The cofunction identities apply to complementary angles. Viewing the two acute angles of a right triangle, if one of those angles measures x, the second angle measures π 2 − x. Then sin x = cos (π 2 − x). The same holds for the other cofunction identities. The key is that the angles are complementary.
Cofunction Identities Worksheets. Cos, cot, and cosec are cofunctions of sin, tan and sec, hence they are prefixed with "co".
