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?
9. What is the minimum value of coshx?
10. What is coshx differentiated?
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)
