Question

Which of the following statement is true

  1. sin h to the power of 2 end exponent invisible function application x minus cos h to the power of 2 end exponent invisible function application x equals 1    
  2. sin h to the power of 2 end exponent invisible function application x plus cos h to the power of 2 end exponent invisible function application x equals 1    
  3. sec h squared x minus tan invisible function application h squared x equals 1    
  4. cot h to the power of 2 end exponent invisible function application x minus text cosec end text text h end text to the power of 2 end exponent x equals 1    

The correct answer is: cot h to the power of 2 end exponent invisible function application x minus text cosec end text text h end text to the power of 2 end exponent x equals 1


    It is obvious.
