6. What is the exponential form of sinhx?

  • 1/2 (e^x - e^-x)
  • 1/2 (e^x + e^-x)
  • 1/2 (e^-x - e^x)

7. How would you derive the inverse of a function?

  • Find the reciprocal
  • Switch y and x in the equation, then find x in terms of y. Use an identity eg.cosh^2x-sinh^2x=1, tanh^2x=sec^2x
  • Differentiate the inverse function using the formula book

8. What is sinhx differentiated?

  • Tanhx
  • Coshx
  • -coshx

9. What is the minimum value of coshx?

  • - infinity
  • 1
  • 0

10. What is coshx differentiated?

  • Sinhx
  • Tanhx
  • -sinhx

11. What is the exponential form of coshx?

  • 1/2 (e^-x - e^x)
  • 1/2 (e^x + e^-x)
  • 1/2 (e^x - e^-x)
