T.RathodFormer Professor, Department of Mathematics, Central College, Bengaluru-560001Journal Article20210921We consider the application of splines to function and integral function approximations, where the integral function refers to the indefinite integral whose lower limit is a constant and upper limit is a variable or function of a variable. Integral function approximation are very useful, one simple and immediate application refers to the construction of a table of integral for example the table of logarithms, normal distribution etc, other applications are possible in the evaluation of multiple integrals over triangular and tetrahedral regions to name a few.http://www.journal-aquaticscience.com/article_137277_af79a522a1f8ca3cf6fc98b474458d79.pdf
