(See graph at bottom ) Below is a picture of the graph of cos (x) with over the domain of 0 ≤x ≤4Π with cos -1 (-1) indicted by the black dot.The cosine calculator allows through the cos function to calculate online the cosine of an angle in radians, you must first select the desired unit by clicking on the options button calculation module. After that, you can start your calculations. To calculate cosine online of π 6, enter cos ( π 6), after calculation, the result 3 2 is returned. Oct 28, 2015 · cos^{-1}0=pi/2 graph{cosx [-7.855, 7.856, -3.93, 3.925]} cos^{-1} is an angle x, for which cos x=0. If you look at the graph of f(x)=cosx you see that cosx=0 for x=pi/2+kpi for any k in ZZ, so the smallest positive value is pi/2 Dec 20, 2016 · 1/2 cos(cos^-1(1/2)) . let cos^-1(1/2)=A :.cosA=1/2=cos(pi/3) :.A=pi/3 or cos^-1(1/2)=pi/3 So , cos(cos^-1(1/2)) = cos (pi/3) =1/2[Ans] As you can see below, the cos -1 (1) is 270° or, in radian measure, 3Π/2 . '-1' represents the minimum value of the cosine function ever gets and happens at Π and then again at 3Π ,at 5Π etc.. (See graph at bottom ) Below is a picture of the graph of cos (x) with over the domain of 0 ≤x ≤4Π with cos -1 (-1) indicted by the black dot..
