Sinhx 3 of 9 What is sinhx differentiated? Coshx 4 of 9 What is sechx as a fraction? 1/coshx 5 of 9 What is cosechx as a fraction? 1/sinhx 6 of 9 What is the minimum value of coshx? 1 7 of 9 How would you derive the inverse of a function? 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 8 of 9 When finding the inverse of coshx, what limitation must be applied and why? x > 0, so that coshx is a one-to-one function 9 of 9
