Question

how to calculate integral without limits from scientific calculator? If anyone knows ,plz help...its urgent

Answer 1

use geometric shapes... I am not sure what you are asking for-:(

Answer 2

are you dealing with a particular problem?

Answer 3

I want to calculate integration from scientific calculator
\[\int\limits\limits x+3x \]

Answer 4

sure,
\[\int\limits_{ }^{ }x+3x~dx\]you mean

Answer 5

x+3x = 4x

Answer 6

i can calculate integral with limits on calculator bt dont know how to calculate without limits

Answer 7

Mr is right, add them, and take the constant out

Answer 8

\[\int\limits_{ }^{ }x+3x~dx=\int\limits_{ }^{ }4x dx = 4 \times \int\limits_{ }^{ }x ~dx=?\]

Answer 9

I have to calculte it using calculator.....not by solving. I have randomly written the expression, Actually i want to know the method of solving integration on scientific calculator

Answer 10

\[Power~rule:~ \int\limits_{ }^{ } x^n~~dx=~~\frac{1}{n+1}x^{n+1}+C\]

Answer 11

I see, idk how to use the calculator for that. (Nor do I see any purpose in doing that)

Answer 12

it should be a definite integral, shouldn't?

Answer 13

we have to solve complex integration questions, which take huge time to solve manually

Answer 14

but your problem is just an indefinite integral, and you have to use a calculator, or is it a definite integral?

Answer 15

indefinite

Answer 16

idk how to sorry-:(

Answer 17

its ok....n.p

Answer 18

can you post your integral?

Answer 19

I just want to know the basic method of solving any integral(without limits) on scientific calculator

Answer 20

freckles it is, as he said.\[\int\limits_{ }^{ }(x+3x)~dx\]

Answer 21

oh i thought it was a little more complex than that

Answer 22

because he said it was really complex

Answer 23

i have typed this expression randomly to know the method......In exams , several logarthmic and exponential funtions are combined in an expression.......which takes huge time to solve manually

Answer 24

it sometimes depends on the calculator
i have only ever known handheld calculators to approximate definite integrals

Answer 25

I also know how to calculate definite integrals........bt I have to calculate indefinite integrals

Answer 26

have you tried looking up your model of calculator and seeing if it can actually perform this task you want it to
or if you want me to look it up i need to know the model of calculator

Answer 27

fx 991 ES plus
fx 991 MS

Answer 28

if i didn't read this wrong the answer is no

Answer 29

For what it's worth, I have yet to hear of a scientific handheld calculator that can take antiderivatives. As far as I know, most calculators only have a definite-integral function.

Answer 30

if it is an indefinite integral then the answer is an equation, NOT a value. I can't see how a calculator could do this for any except the most trival equations.

Answer 31

yes i need the answer as an equation

Answer 32

Wolfram can handle lots of integrals.

Answer 33

for this particular integral ? or as a general rule?

I think you are expecting too much from a calculator - integration can rapidly become a complex process - you need to analyse the method required and the rules and the constant of integration.......

Answer 34

i need to know general method

Answer 35

@1234sd I looked up your model and a bunch people said you couldn't do it with that model.

Answer 36

for the integral \(\int_a^bf(x) \ dx\)

On a TI-89

`int(f(x), x, a, b)`

for \(\int f(x) \ dx\) use

`int(f(x),x)`

int is the little integral sign above the 7

Answer 37

it will not retricethe constant, so you need to do that....

i.e. for \(\int 2x \ dx\) it will give the answer as \(x^2\) you need to add the constant so \(x^2+c\)

Answer 38

@SithsAndGiggles ti 89 will most definitely handle indefinite integrals.

Answer 39

I would have expected it as a feature on the NSpire model, but not the TI-89. Good to know! I guess I hadn't considered graphing calculators as "scientific" for some reason.
