Please use assembly language in the simplest form possible. Please don't copy the previous work, I am looking to check the code itself.
Find the infinite series for SIN(X) in a calculus book and implement it in a subroutine called SIN. Use EPOWER as an example of how to do this.
EPOWER is as follows:
;Program SIN.ASM: Software driver program for SIN procedure.
.MODEL SMALL .DATA X DB 0,1,0,0,0 TEMP DB 5 DUP(?) ETOX DB 5 DUP(?) ZERO DB 0,0,0,0,0
.CODE .STARTUP CALL EPOWER .EXIT
EPOWER PROC FAR LEA SI,ZERO ;predefined constant 0 LEA DI,ETOX CALL FAR PTR COPY ;clear result MOV CX,10 ;init loop counter
NEXTERM: LEA SI,X ;compute numerator MOV AL,CL CALL FAR PTR POWER LEA BX,TEMP ;save numerator CALL FAR PTR SAVE MOV AL,CL ;compute denominator CALL FAR PTR FACTORIAL LEA SI,TEMP ;divide to generate term XCHG BP,DI CALL FAR PTR DIVIDE XCHG BP,DI ;add current term to result LEA SI,ETOX CALL FAR PTR ADDER LEA BX,ETOX ;save result CALL FAR PTR SAVE LOOP NEXTERM RET
If possible, please use the Taylor Expansion. Example,
algebraic formula : x - (x^3/3!) + (x^5/5!)
RPN : x x x * x * 3 2 * / - x x * x * x * x * 5 4 * 3 * 2 * / +...
