It is interesting to note that the value of cos changes according to the quadrants. In the above table, it can be seen that cos 120°, 150° and 180° have negative values while cos 0°, 30°, etc. have positive values. For cos, the value will be positive in the first and the ...

You can find approximate cosine values without acalculatorby using the cosine ratio. Cosine A is equal to the length of the leg adjacent to angle A divided by the length of the hypotenuse. How do you convert cosine to an angle? To convert a cosine value to an angle, you need to find...
x Angle in radians.Return ValueThe cosine or hyperbolic cosine of x. If x is greater than or equal to 263, or less than or equal to –263, a loss of significance in the result of a call to cos, cosf, or cosl occurs.By default, if the result is too large in a cosh, coshf, ...
