I'm excited about going back to 'Today,' but, at odd moments, I'll grit my teeth in anxiety. I feel like a student before the start of school. I've got my new shoes and my book bag, but I'm not sure I'll remember how to do trigonometry. During my maternity leave, I haven't used many words of more than one syllable.

A lot of times, when kids have problems with algebra or trigonometry, it has nothing to do with the subject matter, has nothing to do with their innate intelligence. It's just they that they had some gaps in elementary school that they never got to fill in.

American Educator

I am all for trying to teach household finance in schools, starting as early as possible. And when it comes to high school, I think learning about compound interest is at least as important as trigonometry or memorizing the names of all 50 state capitals.

I was not allowed to take spherical trigonometry because I'd sprained my ankle. Because I'd sprained my ankle, I had an incomplete in gym, phys ed. And the rule was that if you had an incomplete in anything, you were not allowed to take an overload.

Fractions, decimals, algebra, geometry, trigonometry, calculus, mechanics - these are the steps up the mountain side. How high is one going to get? For me, the pinnacle was Projective Geometry. Who today has even heard of this branch of mathematics?

Terence Tao

Math education has changed over the years. In the 19th century, they taught spherical trigonometry because one of the biggest applications of mathematics was navigating the ocean. This is no longer so relevant.

I love reading poetry, and yet, at this point, the thought of writing a poem, to me, is tantamount to figuring out a trigonometry question.

American Author

Can you imagine young people nowadays making a study of trigonometry for the fun of it? Well I did.

I'm an artist; I'm not going to use trigonometry.

Trigonometry is a specific branch of mathematics, not just a general term for math.

Mathematical Branch

The focus of trigonometry is strictly on triangle shapes and their properties.

Triangle Focus

Trigonometry applies to various real-world situations, like engineering and physics.

Real-world Application

 - OK. - Because all that? - There are fancy words for you. You're going to move the concrete and the steel. - That's what I like to hear. - That's it. So first thing, you'll need some protective gear. So there's some glasses and gloves you're going to need throughout the day, and here is a pen and paper in case you want to take notes. That's your call. - Notes? - A foreman take notes? - I didn't come to do trigonometry. - OK, that's your call.

 Now, those of you taking trigonometry, that particular type of math is very useful for making maps like this because it allows you to measure heights and distances without actually having to go there. In fact, the more I mapped and studied caves, the more useful I found all that math that I originally hated in school to be. So, when you're done surveying, you take all this data,

 Do it as long as necessary, until you have mastery. The traditional model, it penalizes you for experimentation and failure, but it does not expect mastery. We encourage you to experiment. We encourage you to fail. But we do expect mastery. This is just another one of the modules. This is trigonometry.

 and now I'm being pushed to the more advanced thing. And this will continue for months, years, all the way until at some point, I might be in an algebra class or trigonometry class and I hit a wall. And it's not because algebra is fundamentally difficult or because the student isn't bright.

 you need to mulitply the x and the y coordinates all by two. So, this shows us that the mathematics of scaling is mulitiplication. Okay? How about this one? How about rotation? Alright, spinning around. The mathematics of rotation is trigonometry.
