Look at the graph of the cos-1 function: you can see its domain. In the graph, we also see that the range of arccos is the interval [0, π] (in radians: it equals the range [0,180°] in degrees). This is because the cosine is a periodic function; in particular, it is not ...
How to Find Cos 3° in Terms of Other Trigonometric Functions? Usingtrigonometry formula, the value of cos 3° can be given in terms of other trigonometric functions as: ±√(1-sin²(3°)) ± 1/√(1 + tan²(3°)) ± cot 3°/√(1 + cot²(3°)) ...
