Question

if m cotA = n, find the value of

Answer 1

\[\frac{ msinA-ncosA }{ ncosA+msinA }\]

Answer 2

@TheSmartOne, a lil help here? ;-;

Answer 3

divide the numerator and denominator by sinA first

Answer 4

Oh, so it becomes \[\frac{ m-n * n/m }{ n * n/m + m}\]

Answer 5

Yea? ;-;

Answer 6

no cheating :P

Answer 7

Whut do u mean? o.o

Answer 8

I did what u asked me to xD

Answer 9

What do we do from there?

Answer 10

I know you're cheating because you did my step somewhere else and did another step and gave me that result :P

We divide by sinA in both the numerator and denominator because that will give us some 1's and cos/sin which is cot

so first divide both the numerator and denominator by sinA and simplify :)
