Question

c o s h to the power of 4 end exponent left parenthesis x right parenthesis minus s i n h to the power of 4 end exponent left parenthesis x right parenthesis equals

  1. c o s h blank x    
  2. cosh2 x    
  3. sinh invisible function application x    
  4. sinh2 x    

The correct answer is: cosh2 x


    cosh to the power of 4 invisible function application x minus sinh to the power of 4 invisible function application x equals cosh invisible function application 2 x
