sin cos tan in assembly language in marie

u send me this code

SIN DEC $0$ ; Initialize SIN register to $0$

LDA ARG ; Load argument $($angle in radians$)$ into AC

JSUB ABS ; Take absolute value of angle

STA ABS ; Store absolute value in ABS

LDA ABS ; Load absolute value into AC

ADD PI ; Add PI $($limit angle to first quadrant$)$

JSUB MOD ; AC $=$ AC modulo $2$PI $($take angle in first revolution$)$

STA ARG ; Store reduced angle in ARG

LDA ARG ; Load reduced angle into AC

JSUB SQR ; Square the angle $($ARG$^2)$

STA TEMP ; Store ARG$^2$ in TEMP

LDA ARG ; Load ARG into AC

STA SIN ; Initialize SIN to ARG $($first term in series$)$

LDA ONE ; Load constant $1$ into AC

STA FACT ; Initialize FACT to $1$

LDA THREE ; Load constant $3$ into AC

STA N ; Initialize N to $3$

LOOP LDA SIN ; Load current SIN value into AC

MUL NEG ; Negate AC $($alternate signs in series$)$

MUL TEMP ; Multiply by ARG$^2$

DIV FACT ; Divide by N$!$

DIV N ; Divide by N

ADD SIN ; Add to current SIN value

STA SIN ; Store new SIN value

LDA FACT ; Load current FACT into AC

MUL N ; Multiply by N

STA FACT ; Store new FACT

ADD TWO ; Increment N by $2$

STA N

LDA N ; Load N into AC

ADD ONE ; Add $1$ to N

JSUB SQR ; Square $($N$+1)^2$

SUB TEMP ; Subtract ARG$^2$ from $($N$+1)^2$

BRP LOOP ; Loop if positive $($continue approximation$)$

JSUB SGN ; Determine sign of original ARG

MUL SIN ; Apply sign to SIN

STA SIN ; Store final SIN value

$...$ ; Rest of program

but there is no multiblication and divion in marie

any solution??
