Webyou want to find the cofunction of cos (2pi/7) that would be sin (90 degrees - 2pi/7) 90 degrees is equal to pi/2, so you would get: cos (2pi/7) = sin (pi/2 - 2pi/7). pi/2 is equivalent to 7pi/14 2pi/7 is equivalent to 4pi/14 your equation becomes: cos (2pi/7) = sin (7pi/14 - 4pi/14) which can be simplified to: cos (2pi/7) = sin (3pi/14) WebTo find the value (s) of cosine, it is common to reference a table of cosines, use a calculator, or approximate using the Taylor Series of cosine. In most practical cases, it is not necessary to compute a cosine value by hand, and a table, calculator, or some other reference will be provided. Cosine calculator

WebSep 15, 2024 · sinA = cos B sec A = csc B tanA = cot B sinB = cos A sec B = csc A tanB = cot A We say that the pairs of functions { sin, cos }, { sec, csc }, and { tan, cot } are cofunctions. So sine and cosine are cofunctions, secant and cosecant are cofunctions, and tangent and cotangent are cofunctions. WebA: Click to see the answer.
