Question

If sin invisible function application x plus c o s e c blank x equals 2 comma then sin to the power of n end exponent invisible function application x plus blank c o s e c to the power of n end exponent x is equal to

  1. 2  
  2. 2 to the power of n end exponent  
  3. 2 to the power of n minus 1 end exponent  
  4. 2 to the power of n minus 2 end exponent  

The correct answer is: 2


    sin invisible function application x plus blank c o s e c blank x equals 2
    rightwards double arrow open parentheses sin invisible function application x minus 1 close parentheses to the power of 2 end exponent equals 0
    rightwards double arrow sin invisible function application x equals 1
    rightwards double arrow sin to the power of n end exponent invisible function application x plus c o s e c to the power of n end exponent x equals 1 plus 1 equals 2
