What is the arccos of 0 ? arccos 0 = ? The arccosine is the inverse cosine function. Since cos 0 = cos 0º = 1 The arccosine of 0 is equal to the inverse cosine function of 0, which is equal to π/2 radians or 90 degrees: arccos 0 = cos-1 0 = π/2 rad = 90º See...

Does cosine repeat? The cosine function is periodic with a period of 2π radians (or 360° in degrees), meaning its values repeat at regular intervals due to the unit circle’s periodic nature. Trigonometry CalculatorsMath Calculators
The inverse cosine of 0 is π/2 radians or 90 degrees. This is because the cosine function has a maximum value of 1 at 0 radians and the inverse cosine function takes a value of 0 at π/2 radians, which is the midpoint of the cosine function’s range. Thus, cos-1(0) = π/2...
the function the value of which for a given argument between –1 and 1 is the angle in radians (between 0 and π), the cosine of which is that argument: the inverse of the cosine function Collins English Dictionary – Complete and Unabridged, 12th Edition 2014 © HarperCollins Publishers...
Move the mouse around to see how different angles (in radians or degrees) affect sine, cosine and tangent.In this animation the hypotenuse is 1, making the Unit Circle, which is like a map for trigonometry.Notice that the adjacent side and opposite side can be positive or negative, which ...
