2. What is coshx differentiated?
- Sinhx
- Tanhx
- -sinhx
3. 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
4. Which of these identities is correct?
- cosh^2(x) - sinh^2(x) = 1
- cosh^2(x) + sinh^2(x) = 1
- cosh^2(x) - sinh^2(x) = cosh(2x)
5. 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)
