Mathematics Corner :)

:sl:

Okay, using seekre of ilm's method, I have tried to get the answer for a similar question:



81 = 3 (to the K)

Log 81 = Log 3 (to the K)

Log 81 = K Log 3

Log 81/Log 3 = K

k = 4

Have you all got the same or is it totally wrong?

Wasalam

salams,

could you plug any sample problems that u got issues with? its always best explaining things with an actual problem in mind.

all the best

one question on da topic is:

the orbit of the moon around the earth may be modelled as circular. The time taken 4 the moon 2 make 1 complete orbit is approx 27.32 days.

a) Show that the angular speed of the moon is approx 2.66 X 10tothepower6 radians per sec

b) Assuming that the radius of the circular orbit is approx 3.844 X 10tothepower8 metres, find the speed of the moon, relative 2 the earth, in metres per sec

its an exam type question and i dont understand how 2 work it out, do u think u can help?

I think i can help you out with this math problem but i would have to think it through at home today... I will start on it as soon as i get home...

NOTE: guys don't let this topic die.. post some problems :)

I'm still struggling with Maths.. In a perfect world, either Maths didn't exist or I had more talent in that subject. :exhausted The latter is almost an impossiblity. :-[ *sigh*

Where, oh where did those mathematical genes get lost, that both of my parents so strongly possess? Oh yes! To both of my younger sisters. :rollseyes



I will come to this thread as soon as school starts again, inshaAllah!
 
Mashaa'Allah I didn't know you went to school. Sister, you come across as somebody who is much older and intelligent!
 
Oh, jazakAllah kheyr for that! Same applies to you, mashaAllah. But I am not sure if you do go to school aswell.. Do you?

I'll be 18 in August. There's plenty of school left for me. :D

JazakAllah Khayr. I'll be 18 next April but I'm in college. When you say school...do you mean college? Because I'm pretty sure 17 year olds go to college!

We iyyak.

English is my 5th language and I use it only online so I don't bother much, I just say school... But correctly said I believe it is to say that I visit an upper secondary school.

You're younger than me. :skeleton:

The attitude that many of us Brits take is very much 'Everyone else learns English so why should we bother learning other languages?'.

But not me! :D My parents are from Mauritius so I know Creole which is their language (very similar to French). I got a GCSE in German and French and I'm also doing an A-level in French but I can barely hold a conversation in either of these languages, let alone speak them fluently on an online forum. Argh...so frustrating.

Anyway...
