Abstract : The report supplements the work of 'The Problem of Integration in Finite Terms,' (AD-651 587) by modifying the results there so that they apply to elementary functions built up with real operations as sin, 1/tan, cosh, etc. It is shown that if a function is given to us in a real form, its elementary integral, if it exists, must also be expressible in a real form, i.e., without the use of complex numbers. Also, shown is the use of the algorithm of section 3 of the aforementioned paper to integrate real elementary functions. (Author)
