O-Level Additional Math

[skyjuice]

Any one has a tuition centre to recommend for Sec 2 Math? Right now DS is borderline pass case but need a quick jump to at least 70 to be offered a Double Science class next yr.


We put up in Bukit Merah area but don’t mind travelling a bit if the teacher is gd. I just checked Learning Lab and its fees are $900+ a term. Is this the going rate for Sec Math classes?

Hello,


Helping my niece ask this qn:

Find an expression f(x) such that d/dx [f(x)] = 1/(xlnx)

Thanks for help.

Thanks for help.

d/dx [f(x)] = 1/(xlnx)

= (1/x ) / (ln x)

f(x) = ln (ln x) + c (Ans)

hello can i get help for the following algebra question…


(m+2)/3 + 2(m-5)/4

Sorry new to algebra solved untill 10m-22 / 12 stuck after it

Sorry new to algebra solved untill 10m-22 / 12 stuck after it

(m+2)/3 + 2(m-5)/4

= [(m+2)*4]/(3*4) + [2(m-5)*3]/(4*3)

= [ (4m+8)+ (6m-30) ] / 12

= (10m-22) / 12

= (5m-11) / 6 (Ans)

Sorry new to algebra solved untill 10m-22 / 12 stuck after it

(m+2)/3 + 2(m-5)/4

= [(m+2)*4]/(3*4) + [2(m-5)*3]/(4*3)

= [ (4m+8)+ (6m-30) ] / 12

= (10m-22) / 12

= (5m-11) / 6 (Ans)

actually the answer in my math handbook is 5m-5/6 and i typed the equation wrongly :oops:

correct equation

(m+2)/3 + 2(m-5)/4 +1
