The inverse cosine formula is: y = cos(x) | x = arccos(y) Thus, if y is equal to the cosine of x, then x is equal to the arccos of y. Inverse Cosine GraphIf you graph the arccos function for every possible value of cosine, it forms a decreasing curve from (-1, π) to (...
And here is Cosine and Inverse Cosine plotted on the same graph: Cosine and Inverse Cosine They are also mirror images about the diagonal. And Inverse Cosine gets chopped off too.Graphs of Tangent and Inverse TangentAnd here is the tangent function and inverse tangent. They are also mirror ...
When working with theinverse of a function, we learned that the inverse of a function can be formed by reflecting the graph over the identity liney = x. We also learned that the inverse of a function may not necessarily be another function. Look at the sine function (inred) at the righ...
Inverse cosine We’re going to repeat the procedure from the previous section: Notice that the graph shows that cos^{−1} is neither even nor odd, which is despite the fact that cos(x) is an even function of x. And it has domain [-1,1] and range [0,\pi] y=cos^{-1}(x)\...
A function ff is one-to-one if and only if every horizontal line intersects the graph of ff no more than once. Figure 2. (a) The function f(x)=x2f(x)=x2 is not one-to-one because it fails the horizontal line test. (b) The function f(x)=x3f(x)=x3 is one-to-one because...
Graph of y = cos x. We now choose the portion of this graph from x = 0 to x = π, shown here by the shaded portion: 0.5ππ-0.5π0.511.522.53-0.5-1xy Graph of y = cos x with shaded portion 0≤x≤π0≤x≤π. The graph of the inverse of cosine x is found by reflecting ...
The graph of f(x) and f-1(x) are symmetric across the line y=xExample: Square and Square Root (continued) First, we restrict the Domain to x ≥ 0: {x2 | x ≥ 0 } "x squared such that x is greater than or equal to zero" {√x | x ≥ 0 } "square root of x such ...
What is the cos inverse of zero? The answer is90°, that is,π/2 rad. One way to get this result is to reformulate the question and askwhat is the angle that lies in the interval [0, π] and its cosine is zero?It may help to sketch the cosine graph (the usual wavy stuff) an...

In this chapter, we discuss the inverse cosine and inverse tangent functions, and their application to the solution of the basic equations cosx=Aand tanx=A. As we mentioned, in order to construct the inverse function, we need to select a monotonic interval with the maximum length in the ...
