2. 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 finished… You 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 p=q=1?
What happens if we change the values of
p & q (where p & q are real constants)?

5. Cartesian and parametric forms
Unit circle

6. Cartesian and parametric forms
Rectangular hyperbola
Difference of two squares:

7. let
But notice the restriction that now t>0

8. Compare!

9. What do these hyperbolic functions look like?

10. What do these hyperbolic functions look like?

11. Cartesian and parametric forms
Rectangular hyperbola
These are not the standard parametric equations that are generally used, can you say why not?
are used

12. Complex variables, z
Replace z by iz
Replace z by iz

13. Complex variables, z
Replace z by iz
Replace z by iz

14. 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. Osborn’s rule
“… change each trig ratio into the comparative hyperbolic function, whenever a product of two sines occurs, change the sign of that term…”

19. Differentiation

20. Integration
