The website has your answer. The t-distribution is a regularized
incomplete beta function. The incomplete beta function is given by R's
pbeta function. You regularize it with R's beta function. Then you use
R's uniroot function to find the inverse. Good homework problem.

No, that's correct. Actually, I have data set below;

degree of freedom= 1223-2= 1221
