then what?

  • ganeshie8
on left hand side, you're seeing 1-sinx in bottom, so multiply & divide 1-sinx
ganeshie8
  • ganeshie8
1 + sin x 1-sin x __________ x ---------- cos x 1-sin x
yamyam70
  • yamyam70
Hmm.. why did you multiply the left side with the result of the right hand side, is that possible?
ganeshie8
  • ganeshie8
i have just multiplued wat u have wid \(1\) 1-sin x ---------- = \(1\) 1-sin x
ganeshie8
  • ganeshie8
u have this 1 + sin x __________ cos x
ganeshie8
  • ganeshie8
multiply it 1,
ganeshie8
  • ganeshie8
1 + sin x __________ x \(1\) cos x
yamyam70
  • yamyam70
is this rationalizing?
ganeshie8
  • ganeshie8
1 + sin x 1-sin x __________ x ---------- cos x 1-sin x
yamyam70
  • yamyam70
please go on
ganeshie8
  • ganeshie8
kindof, but there are no rationals involved here :) its all trig simplify now
ganeshie8
  • ganeshie8
use this : \((a+b)(a-b) = a^2-b^2\)
yamyam70
  • yamyam70
I see :)
ganeshie8
  • ganeshie8
1 + sin x 1-sin x __________ x ---------- cos x 1-sin x (1-sin^2x) ---------- cos x (1- sinx)

and then we use the phytagorean identity ?
ganeshie8
  • ganeshie8
rest is bit easy :)
ganeshie8
  • ganeshie8
yeah
yamyam70
  • yamyam70
Thanks :)
ganeshie8
  • ganeshie8
u cud have solved this by taking left hand side also
ganeshie8
  • ganeshie8
cosx ______________ = sec x + tan x 1 - sin x take left hand side, cosx ______________ 1 - sin x
ganeshie8
  • ganeshie8
now multiply & divide it wid \(1\)
ganeshie8
  • ganeshie8
give it a try when free :)
yamyam70
  • yamyam70
1 + sin x / 1 + sin x ?
ganeshie8
  • ganeshie8
Yes !
yamyam70
  • yamyam70
oh my gosh thanks :)
ganeshie8
  • ganeshie8
np :)

  • yamyam70
I will close this now, bye :) see you
