sin [\(\theta\)-30] = 1 = sin 90
hartnn
  • hartnn
got that ^ ?

  • DLS
i didnt get that diag! but yes what u said
DLS
  • DLS
okay got the diag too
hartnn
  • hartnn
so, theta =... ?

pi/2 right?what else :/

hartnn
  • hartnn
that means , you didn't get this... sin [θ-30] = 1 = sin 90

im getting embarassed with so many people viewing this ques lloll

Interesting question :P
hartnn
  • hartnn
dls, write the step till how much u understood totally.
DLS
  • DLS
okay
DLS
  • DLS
why did we interchange the values cos a = \sqrt 3/2 ,sin a =1/2? we had sin with sqrt 3/2 and cos with 1/2
hartnn
  • hartnn
when did we have sin with sqrt 3/2 ?? and you can take that also, then u have to use a different formula.
DLS
  • DLS
ur first post O_O
hartnn
  • hartnn
\(\LARGE (\sqrt{3}/2)\sin \theta-(1/2)\cos \theta=2/2\) \(\LARGE \cos 30\sin \theta-\sin 30\cos \theta=1\) \(\sin(\theta-30)=sin 90 \\ \theta =...?\)
DLS
  • DLS
120?
hartnn
  • hartnn
yes, u got it ?
DLS
  • DLS
yes..much better when u wrote that together !! and we had less people lol
DLS
  • DLS
we have only ONE possible value?
DLS
  • DLS
okay thats obv..thanks! and thanks to the spectators >>
hartnn
  • hartnn
u want general expression ?
DLS
  • DLS
sure
DLS
  • DLS
but thats not reqd.i just wanted to know the possible values of theta from 0 to 2pi
hartnn
  • hartnn
then only 120
DLS
  • DLS
yes..thats it!thanks!
