1. Sinbad &
Cosette
A trigonometric love story

2. once upon a time. . .

3. There were two families…
the Tanu the Tanv
family family

4. The families
were great
friends and
enjoyed
spending
time together
as their
children grew
up.

5. Once Sinbad and Cosette got to high
school, things changed. Sinbad, after
spending so much time with Cosette
as a child, fell in love with her.

6. Unfortunately, Cosette didn’t feel
the same way.

8. Sinbad made his brother and Cosette’s sister sit
together in the back seat while he and Cosette sat
in the front.
Sinbad loved to tell people that his and
Cosette's signs were the same.

9. If Cosette drove, she
made sure that
Sinbad sat in the
backseat with his
brother and her
sister sat in front.
She made sure everyone knew that
their signs were NOT the same.

10. Sinbad was ecstatic when the families got
together, but Cosette was miserable. She
was the only one of the two families that
didn’t enjoy their time together.

11. How does the story end?
Like a lot of teenagers, Sinbad and Cosette moved on. They
both went to college, found new people to love, got
married, and had kids. But 60 years later, when both of
their spouses had passed away of natural causes, they
happened to meet up again….

12. and they lived happily
ever after.

13. The Moral of the Story:
Some of the people to whom we are attracted
are not attracted to us. It is not unusual for a
person who has shown interest in us to later
lose interest in us. Maybe that is a good thing,
because it forces us to date a lot of people and
to become more experienced in maintaining
relationships.

14. The 2 nd Moral of the Story:
Trigonometry is everywhere!

15. TO SUMMARIZE:
When Sinbad drives:
sin(u + v) =
When Cosette drives:
cos (u + v) =
When the families get together:
tan (u + v) =
