In Exercises 13–24, find the derivative of y with respect to the appro-
priate variable.
1
14. y = sinh (2x + 1)
х
13. y = 6sinh
15. y = 2Vitanh Vi
16. y = t²tanh-
18. y = In(cosh z)
17. y = In (sinh z)
19. y = (sech 0)(1 – In sech 0) 20. y = (csch 0)(1 – Incsch 0)
tanh? v
coth v
21. y = Incosh v
22. y = In sinh v
23. y = (x² + 1) sech (In x)
(Hint: Before differentiating, express in terms of exponentials and
simplify.)
24. y = (4x² – 1)csch (In 2x)
