1. A trigonometric love story
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
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.

7. When Sinbad and Cosette went out together with their group of friends and Sinbad was driving the car, he made sure to arrange it so he and Cosette could spend some time together.

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 2nd Moral of the Story:
Trigonometry is everywhere!

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