Thank you Only your last step is wrong If you take the reciprocal of the answer you have it will be right
yes the last step cos / sin isnot tan ,, sin / cos is tan so it will be ( cos / sin ) = - square root ( 3 ) => 1/tan = -square root (3) => tan = 1/-squr root 3 got it ?
AAH thanks, can't actually believe that I did not spot that myself! I know that cos/sin does not equal tan, but was not looking at it properly.
it happens tweety
