To integrate say f(x)=1/x between A and B (stored in registers A and B), use the following code
Code:
LBL A
RCL A
RCL B
FN= B
<integral symbol> FN d X
RTN
LBL B
INV(X)
RTNLBL B has the EQUATION INV(X) (entered using the EQN feature in program mode). The step FN= B (you press the FN= and then press RCL B) tells the machine that the function to be integrated is in LBL B. The step <integral symbol> FN d X (you press the integral symbol and then RCL X) involves the integration using variable X which also appears in the equation INV(X) located after LBL B. The limits of the integration are in the stack, supplied by registers A and B (for the lower and upper integration limits).
