cos(22) is a trigonometric ratio and, if the angle is measured in degrees, its value is 0.9272
The actual value depends on the argument. The ratio sinh x / cosh x can be written as tanh x. This is analogous to the trigonometric functions.
Trigonometric functions are calculated using a polynomial approximation. The exact polynomial used may be different on different calculators.
Use and rearrange the sine ratio: 30*sin(45) = 21.21320344 units
The solution is found by applying the definition of complementary trig functions: Cos (&Theta) = sin (90°-&Theta) cos (62°) = sin (90°-62°) Therefore the solution is sin 28°.
