Abstract

PURPOSE:To make definite integral easily possible for a key-input optional function, by making it possible to input the function to be integrated preliminarily. CONSTITUTION:The entry mode of a function to be integrated is set by operations of MODE key 7a and entry keys of key input part 7, and function 1/(X+1) is written into RAM9 by the key operation. Next, the mode is switched to the integration execution mode by operations of MODE key 7a and entry keys; and when integral section data 0 and 4 and division designation value 2 are entered, 0 and 4 are written in the A register and the B register of RAM memory 9, and operation result 4 of 2n is written as the division number into the N register. When integration execution key EXE 6b is operated under this state, definite integral is executed, and the result is displayed on display part 6 as the integral value.
