Chi-Square Calculating in CL

Questions
1

I know of a way to calculate area under t-curve in the CL:

T = numericValue(“1-\operatorname{cdf}(\operatorname{tdist}(${df}),1)”)

Is there a similar code for chi-square?

Thanks,
Gregg

Desmos does not have a Chi-square distribution function as far as I am aware, so I don’t think it is possible to do this.
