The Inverse Cosine Function (arccos) [I have mentioned elsewhere why it is better to use arccos than cos−1cos−1 when talking about the inverse cosine function.] Let's first recall the graph of y=cos xy=cos x (which we met in Graph of y = a cos x) so we can see ...
Inverse Trigonometric Function:In trigonometry, the inverse function is the reverse of the original trigonometric function. The ratios of the function will also be reversed. For example, if the cosine function is the ratio of base to the hypotenuse, then the ratio of ...
But when we consider the inverse function we run into a problem, because there are an infinite number of angles that have the same cosine. For example 45° and 360+45° would have the same cosine. For more on this see Inverse trigonometric functions. ...
Without finding the inverse, evaluate the derivative of the inverse of the function at the point {eq}x = \pi/4 {/eq} Inverse Trigonometric Function: The inverse of the cosine function is defined by {eq}\displaystyle y = \cos...
Take the inversecosine of both sides of the equation to extract ( x) from inside the cosine. ( x=(arccos)(0)) The exact value of ( (arccos)(0)) is ( (π )/2). ( x=(π )/2) The cosinefunction is positive in the first and fourth quadrants. To find the secondsolution, sub...

A special case of this distribution has the exact inverse cosine function as a probability density function. To our knowledge, despite obvious mathematical interest, such a probability density function has never been considered in Probability and Statistics. Here, we fill this gap by pointing out ...

To find the domain of the function f(x)=cos−1(2−|x|4), we need to ensure that the argument of the inverse cosine function lies within the interval (−1,1). 1. Set up the inequality: We need to ensure that: −1≤2−|x|4≤1 2. Solve the left side of the inequal...
