Question

The minimum and maximum values of cos space x plus 3 square root of 2 sin space open parentheses x plus pi over 4 close parentheses plus 6 are

  1. 1,11
  2. 11,-1
  3. 6,5
  4. 5,6

hintHint:

In this question, we have to find the minimum and maximum values of cos space x plus 3 square root of 2 sin space open parentheses x plus pi over 4 close parentheses plus 6. For this first we will simplify the trigonometric function and later we can find its range as we know a space sin space x plus b space cos space x element of open square brackets negative square root of a squared plus b squared end root comma square root of a squared plus b squared end root close square brackets.

The correct answer is: 1,11


    cos space x plus 3 square root of 2 sin space open parentheses x plus pi over 4 close parentheses plus 6
equals cos space x space plus 3 square root of 2 open parentheses sin space x. cos straight pi over 4 plus cos space x. sin straight pi over 4 close parentheses
equals cos space x plus 3 square root of 2 sin space x. fraction numerator 1 over denominator square root of 2 end fraction plus 3 square root of 2. fraction numerator 1 over denominator square root of 2 end fraction. cos space x
equals cos space x plus 3 space sin space x plus 3 space cos space x plus 6
equals 4 cos space x plus 3 space sin space x plus 6
A s comma space minus square root of a squared plus b squared end root less or equal than a sin space x plus b cos space x less or equal than square root of a squared plus b squared end root
rightwards double arrow negative 5 less or equal than 3 sin space x plus 4 space cos space x less or equal than 5
rightwards double arrow negative 5 plus 6 less or equal than 3 sin space x plus 4 space cos space x plus 6 less or equal than 5 plus 6
rightwards double arrow 1 less or equal than 3 sin space x plus 4 space cos space x less or equal than 11
