Answer 2

trapezoidal rule is a numerical approximation to a definite integral when the integrand is a non-elementary function, like \[\frac{\sin x}{x},e^{x^2}\]

Answer 3

Is Trapezoidal Rule the most easiest rule than in sympsons rule?

Answer 4

is there any formula for this rule?

Answer 6

please answer my question. It is an individual grade for us. Some of my classmate are same to my question

Answer 7

It's Simpson's Rule just to correct your spelling mistake :3.

Answer 8

And Simpson's Rule would give you a much accurate result than the Trapezoidal Rule.

Answer 9

If you were to calculate the area of a region. Most commonly, under a curve.

Answer 10

The Trapezoidal and Simpson's Rule are just another way to finding the area under a curve etc. That's probably all you need to know.

Answer 11

thank you. and where thus this function continous?

Answer 12

If you're in college/university and you're studying a course that relates to this, then they would delve deeper in. But I'm afraid I'm not in college or uni, so I can't help you there.

Answer 13

function continuous? What are you talking about?

Answer 14

but how can i easy calculate trapezoidal rule?

Answer 15

By using your knowledge on the equation for area of a trapezium. What's the equation for the area of a trapezium?

Answer 16

b-a/n

Answer 17

...Have you learnt anything on the area of a trapezium?

Answer 18

Because if you haven't you wouldn't want to delve any deeper on this topic relating to the Trapezoidal rule...

Answer 19

It is b-a/2n the formula for the area of the trapezoidal rule

Answer 20

Yes that's correct. So what are you trying to ask about how to calculate something easily using the trapezoidal rule?

Answer 21

It's easy to calculate the are once you know the trapezoidal rule. That's it.

Answer 22

area*

Answer 23

yes,is there any formula for the trapezoidal rule?

Answer 24

much easier to calculate for trapezoidal i mean

Answer 25

There is no other formula.Only this formula.
∫abf(x)dx=b−a2n[f(x0)+2f(x1)+...+2f(xn−1)+f(xn)].

Answer 26

Dude, all you need to do to make it easier for you, is to use "common sense". That's all you need to have to do questions involving the trapezoidal rule.

Answer 27

I seriously do not contemplating on remembering big equations such as what reya wrote down. Instead, you can use logic to guide you. I've had success not with remembering massive equations and formulas, but using basic knowledge and understanding. That's all there is to it.

Answer 28

contemplate*

Answer 29

thank you.

Answer 30

can i ask about indeterminate forms and improper integral?
