Question

sin squared space x minus cos space 2 x equals 2 minus sin space 2 x if

  1. straight x equals straight n pi divided by 2 comma straight n element of straight I
  2. tan space x equals 3 divided by 2
  3. straight x equals left parenthesis 2 straight n plus 1 right parenthesis pi divided by 2 comma straight n element of straight I
  4. straight x equals straight n pi plus left parenthesis negative 1 right parenthesis nsin minus 1 left parenthesis 2 divided by 3 right parenthesis comma straight n element of straight I

The correct answer is: tan space x equals 3 divided by 2
