Syntax: @T(N, T)
N = a numeric value
T = a numeric value
@T returns the integral of Student's T-distribution with N degrees of freedom from minus infinity to T. The function is given by:
Examples:
@T(14, 35) = 1
@T(F3, G6) = 0.8411029, where F3 = 500, and G6 = 1
@T(C1, C2) = Error - degrees of freedom must be > 0, where C1 = 0 and C2 = -1
