I used to love the branch of mathematics called Trigonometry back in high school. What about you?
I was kinda good at it but never really knew much about it, What exactly is Trigonometry? 
Trig is a study involving lengths and angles of triangles. It was really fun!
Oh yeah I just needed a refresher, I havent messed with trig since high school. Can you get a job with trigonometry? 
Yup its easy to forget without practice. You can jobs in engineering, music and acoustics, astronomy, ecology, and biology!
Wow really? Id love to get a job in music with trigonometry, But Id think itd be hard. Who invented trig anyways?
Trigonometry
Trigonometry (from Greek "trigōnon", "triangle" and "metron", "measure") is a branch of mathematics that studies relationships between side lengths and angles of triangles. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. In particular, 3rd-century astronomers first noted that the ratio of the lengths of two sides of a right-angled triangle depends only on one acute angle of the triangle. These dependencies are now called trigonometric functions.

When asked about whether there would be a second series, Lilley stated, "I never thought about it in the beginning because it was always a one-off thing. I'm not into just cashing in and rolling off into a second series that is not as good. I really enjoyed making the show, so the thought of writing and going back there again is really fun and exciting, but I haven't made a decision on what to do next."
