Question about Texas Instruments TI-84 Plus Calculator
Hii i have the model CASIO fx- 991 ES & in that
1. I need to perform the integration. say for example integration of log(X), For this if i don't want to specify the limits then how should i give the expression because without specifying the limits it is giving syntax error.
2. The second one is if i need to specify the limit as 0 to infinity or -infinity to infinity then how could it be possible in this model?
Please help me in this regard.
Looking forward for the positive reply.
This calculator can only perform NUMERICAL DEFINITE integrals. Which meansyou have to supply the numerical value of the lower limit and the numerical value of the upper limit. The result is a numerical value.
The calculator cannot perform symbolic calculus.
If the function is simple you find the integral in tables of integrals where you will see that INT(log(X)dx=x(log(x)+1). Some calculators that have a CAS (computer algebra system) can manipulate symbolic expression, but not theCasio FX-991ES.
You ask it the value of the integral of log(X) from X=1 to X=3 and it will give you 0.5627748004
Hope it helps
