WitrynaThe trigonometric function are periodic functions, and their primitive period is 2π for the sine and the cosine, and π for the tangent, which is increasing in each open interval (π/2 + kπ, π/2 + (k + 1)π). At each end point of these intervals, the tangent function has a vertical asymptote . Witryna11 lut 2024 · Since the cotangent function is defined as cosine divided by sine ( or as reciprocal tangent, which is defined by sine divided by cosine, respectively) we get that cot 2 ( x) = ( cot ( x)) 2 = ( cos ( x) sin ( x)) 2 = ( cos ( x)) 2 ( sin ( x)) 2 = cos 2 ( x) sin 2 ( x) ∴ cot 2 ( x) = cos 2 ( x) sin 2 ( x) Share Cite Follow
