rashywire: i knw I'll locate u guys, #shaking heads# ehn ehn, so dis is hw life b abi? Hweva, u guys re doing gr8 here. I'm nw here with u guys 2 learn, 2 solve n 2 help. @ omosive, my mentor always tell me d@ nothin is impossible nt until i found myself knwing basic maths n 4rm there I tank God, so u cn do it, a question may take u 5 days 2 tink, buh if u give it 2 another person 2 solve, d@ shows u dnt wnt 2 disturb ur brain. @ Ortarico, calculux, More PALMOIL 2 ur elbows. Lols. Letz drive mathematics pls

Thanks, I'm improving. Lamlad maths is all about thinking mathematically and I think I'm getting there but cramming tinzz is on my mind cos my exam is fast approaching.

Omosivie,:
Baby maths guru in the house!!!! Pls who knows any shortcut for trig ratios or should I cram them? Cos the triangle method is long.

Derz no need 2 cram dem like say sin30=1/2,sin60=sqrt3/2..e.t.c..All u need 2 knw is jst d "diagram" and frm der u can sot out d rest

Mr Calculus: Derz no need 2 cram dem like say sin30=1/2,sin60=sqrt3/2..e.t.c..All u need 2 knw is jst d "diagram" and frm der u can sot out d rest

The diagram is the triangle method and it's kinda long but all is well sha

@OMOSIVIE
let d prob. dat d man leaves up 2 80yrs=P(M)=2/3
and d prob. dat e does nt=P'(M)=(1-2/3)=1/3.
let d prob. dat a woman leaves up 2 80yrs b=P(W)=3/5
and dat she does nt=P'(W)=(1-3/5)=2/5
:(@ least 1 leaves up 2 80yrs)=[P(M)xP'(W)]+[P'(M)xP(W)]
=[2/3x2/5]+[1/3x3/5]
=4/15+3/15=7/12

Thanks, but wat if the question is: Find the probability that only one of them will live up to 80 years.

[Yeapy] it is i mr calculus am getin som temp dificulties postin
i fink i made a mistake in d 1st calculatn o
dat 1 was 4 only 1 leave up 2 80yrs
@ least 1 means 1 and above
P(@ least 1 leave up 2 80yrs)=[P(M)xP'(W)]+[P'(M)xP(W)]+[P(M)xP(W)]
=[2/3x2/5]+[1/3x3/5]+[2/3x3/5]
=4/15+3/15+6/15=13/15

You've just done a great job boss!

All right and thanks prof.

Approximate 48.5 to the nearest whole number...

I believe that this appro has to do with boundaries of a thing . Why not educate us on it like you did on 2go prof.

if u are to educate us biko educate us hear oooooo

Am back on point

For approximation stuff...if we are to approximate to d.p(decimal places)...e.g 2.7253...to 3dp,since the fourth digit to the decimal is 3 and less than 5...therefore,it's neglected...so,it becomes.2.725...if,3.5555.is to be approximated to 2dp...,the third digit to the decimal is 5 but that 5 still has some numbers at the back...so,it's changed to 1 and added to the next one...then it becomes...3.56...let's now go to the main point,if 4.65 is to be approximated to 1dp...the second digit to the decimal is 5(and nothing at the back again)...then the number before the 5 is approximated to the nearest even number...which now become 4.6...but if 4.75 is to be approximated to 1dp or 2sf,then it will be 4.8...

So,for the question 48.5 to the nearest whole number gives 48...that's all...let's use this analogy...find the class interval of 48.then it ranges from 47.5 to 48.5...so,anything in that is approximated to 48...it means 47.5 and 48.5 both have approximation of 48...

Haba, thanks as well. More power to yours too. We can all get started prof!

Let's bring tough questions pals,and let's gain from one another.....here is the first one i have with me here....solve for x,if 2^x=5x+11

It's same as 1/sinx which integral is; -In[cosec(x) + cot(x)] + c
