FP2 (MEI)Hyperbolic functions -Introduction
(part 1)
  • Let Maths take you Further

3
Introduction to hyperbolic functions
  • Before you start
  • You need to be confident in manipulating
    exponential and logarithmic functions
  • You need to be confident all the calculus
    techniques covered in Core 2 and 3
  • You need to have covered chapter 4 on Maclaurin
    series
  • When you have finishedYou should
  • Understand the definitions of hyperbolic
    functions and be able to sketch their graphs
  • Be able to differentiate and integrate hyperbolic
    functions

4
Exploring with Autograph
  • What does the graph look like if pq1?
  • What happens if we change the values of
  • p q (where p q are real constants)?

Cartesian and parametric forms
Unit circle

Cartesian and parametric forms
Rectangular hyperbola
Difference of two squares

These are not the standard parametric equations
that are generally used, can you say why not?

Results
cosh(iz) cos z sinh(iz) i sin z
cos(iz) cosh z sin(iz) i sinh z
15
Circular trigonometric identities and hyperbolic
trigonometric identities
16
Osborns rule
  • change each trig ratio into the comparative
    hyperbolic function, whenever a product of two
    sines occurs, change the sign of that term
