Page claims:
TDIST returns the probability density function for the t-distribution
FALSE! TDIST happens to actually return the CDF (actually 1-cdf(X)), not the PDF. Just plot it for 0≤X≤4, and compare to e.g. Wikipedia. Plot the differential THEN you get the pdf. The Microsoft page does a better job of explaining this by stating that TDIST(X,...) returns the probability of x>X (i.e. 1-cdf(X))
