1x Squared Graph. In probability theory and statistics the chi-square distribution also chi-squared or χ 2-distribution with k degrees of freedom is the distribution of a sum of the squares of k independent standard normal random variables. The graph of the function y x2 is a curve that is called a parabola.
Can you make cosine squared X divided by2 equal to cosine squared x with some constant. Tap for more steps. To reflect the entire function over the x- or y-axis select the xy check box.
Type in any integral to get the solution steps and graph.
The chi-square distribution is a special case of the gamma distribution and is one of the most widely used probability distributions in inferential statistics. This is probably the simplest of rational functions. They are drawn in red. Tap for more steps.
