In this paper, a few formulas are found to approximate the t cumulative
distribution function. The formulas found in [5] to approximate the normal
distributions are used to get good approximations for t. The derived formulas give
good approximation for degrees of freedom greater than 3 and if the exact
probabilities are less than 0.9.
