cos(37 deg) = 0.7986
0.766
Cos(0) = 1
Algebraically it is written as Cos(56) However, on the calculator, make sure your calculator is 'clear' and in 'degree' mode. Cos(56) = 0.559182903.... Cos(56) = 0.5592 ( 4 d.p.) or Cos(56) = 0.559183 (6 d.p.). NB If your calculator is in 'inverse', 'radian' or 'grad(g)' modes you will have an incorrect answer.
This can be done on a graphing calculator by making sure you have your calculator in degrees mode, and then tentering the cos(23). You get an answer of 0.9205048535.
