Thank you.
What about Q1?

Count the numbers/integers falling in between your answers. Remember to count -21, 21 and 0
43

I dont get it

Thank you. Well I never solved questions for iterations before. Which chapter is this? Can u temme, so that I can refer to that chapter.. Thanks.. and so I didnt get the explanation f Q5.
I kept x =1 then 2 then 3, I got different answers. :/ Was I supoose to do this?? I never got 1.804
What about Q1?

Anum96 Also in Q6 how do we know we have to give answer in radian form?

As for your question. Its better if you give your answer in both forms. I always gave two answers to be on the safe side. However, One things for sure. Whenever the question is in terms of pi, you're supposed to give it in radians.

You put x as 1. Correct. Now use this value as x.
For e.g you got 0.354 when x is 1. now put 0.354 as x and so on. You have to keep using your answers. Thats how you solve iterations.

how much times do we do that?

 

[Anum96]

how much times do we do that?

The moment you get the same answer thrice

 

[Anum96]

Answers are usually pretty long. Make sure you use the whole answers, no matter how long they are. Let your calculator handle that.

Thanks a lot.

Q1)(ii) I got least value as -21.6 and greastest as 21.6 so how n can be 43?
Q3(i) why tan theta cant be negative 4?
Q4(i) I got dy/dx = e^x - 8e^-2x. Now how to solve this when dy/dx = 0?
I did like this,
e^x(1 - 8e^-3x) = 0
ln (1/8) = -3x.
Then is it like, x = ln(1/8) / -3 ?
Q5(ii)(iii) No idea.
Thanks.
Anum96 See if u can help me. ^_^

Why do u keep editing your messages? I wouldn't have given you the same detail you know.
