STPM 2017 Term 2 MT Coursework Explained.

##### —00

In the application in science and technology, some definite integrals are difficult to evaluate by the usual integration techniques. It is a common practice to approximate a definite integral by integrating the first few terms of the series expansion of the integrand.

May I know how to get the degree for both Q3 (a)&(b)4?

It is conversion from radian to degree

For 3 a), why the values for T1 is higher than T2, while for 3 b),the values of T2 is higher than T1.

Greater or lesser does not mean anything here. Because they are approximation to the integral. If you never compare with the exact value, it is no point for you to comment about T1 is greater than T2.

For 3 a) and b), why the values for T1 is greater than the value for T2 ?

So, how to continue with comments the validity???

May i know how to find the exact value of T in Q3?

You can find the integral by using elliptic integral calculator

may i know how you make a function to make tabulate your table?tqvm

Which functions are you referring?

how did you tabulate your data? by using brute force to calculate or using a function and make your first column as input and the following column as output to make your table

Hai Sir, how to calculate T exact? / What is the formula for T exact that should be set at Excel?

U have to integrate it

May I know how to get the exact value of T?

You can use elliptic integral calculator online

Why the values of alpha in 3(b) are between 0.25 to 0.70, but not between 1.0 to 2.5(given in question)?

Please refer to the updated question given by MPM.

What is the formula for T exact in 3(a) and (b)?

Hello, I have question how can you get the T exact? I have tried using elliptic integral calculator but still the answer make no sense. If you can show me how you can get the answer that would be great. Thank you

teacher, how to calculate the error T1 with exact? Is it ((T exact-T1)/T exact)*100 ? Thanks in advance

Yes

can u give a full answer ?

No. I never prepare full answer

What formula should I used to obtain degree? Is it formula from T1?

To convert to degree. Multiply 180 and divide pi

hello sir , what is the aim for this coursework actually ?

To check the appropriateness of using numerical methods

Can u even tabulate out T?

The question mention use alternative method to find T1 n T2

The question oso didnt ask for the value of T right?

So is ur method valid or im the one in wrong?

You can ask your teacher for answer. I am showing what I observed from the question.

sir ,wasnt the radian is a/2? why are u directly convert the a into degree instead of a/2?

Sorry. I can’t get what you meant. Which a/2?

The dy/dø should equal to -k^2sinØcosØ / (k^2sin^2Ø)^3/2 ???

Should have negative sign right ??

No
