Arccosine (Arccos) - Definition, Examples, Graph Arccos x
WebMar 23, 2024 · I believe this is what you did. To be clear cosh − 1 4 = ln ( 4 + 4 2 − 1) = ln ( 4 + 15) , which means you can also write arccos 4 = 2 k π ± i ln ( 4 + 15), k ∈ Z. This is an equivalent answer. If we use e i θ = cos ( θ) + i sin ( θ), we can show that cos ( θ) = e i θ + e − i θ 2 or cos ( θ) = cosh ( i θ). While we can find the value of arccosine for any x value in the interval [-1, 1], there are certain angles that are used frequently in trigonometry (0°, 30°, 45°, 60°, 90°, and their multiples and radian equivalents) whose cosine and arccosine values may be worth memorizing. Below is a table showing these angles (θ) in degrees, … See more The following is a calculator to find out either the arccos value of a number between -1 and 1 or cosine value of an angle. See more Generally, functions and their inverses exhibit the relationship f(f-1(x)) = x and f-1(f(x)) = x given that x is in the domain of the function. The same is true of cos(x) and arccos(x) within their respective restricted domains: … See more how many inches are in a kilometer
