He teaches very clearly through deeper head What ever questions use to come inside me means why we do all are clearly done no worries now 😀

I'm not sure I would have shared this version with students.

@@brianrichardcompton381 Yeah those students are suddenly going to find out what drugs are, now!

You forgot 🤷🏻‍♂️🤷🏻‍♂️🤷🏻‍♂️🤷🏻‍♂️

Haha! Very true

😂

yo are u still alive

@@JamesBainbridge-xn7rn of course 🙂

i saw CATS for some reason -_-

@Connor Gaughan yea same

Unless you're a liberal arts student 😂

This goes for me too.

Look up the Taylor Series. It isn't specifically what goes on in the calculator, but it gives you a general idea of the working principle that is easiest to understand, and build yourself. Essentially, it is derivative matching at a given point, so that we find a polynomial that matches the position, slope, and curvature, and higher orders of derivatives, to calculate the function. Actual calculators use other algorithms that are more efficient to compute, but require more advanced knowledge to understand.

@@dipanshusingh6329 Thank you for your recommendation. I will get started with it, very soon :)

If they give a range then you should give your answer according to the range Like 0

Yes. I have heard of that acronym. However I think that it is important to have the first quadrant represented first in the acronym, hence to start with "A".

Ass stick?

When the angle theta is 0 degree, there is no triangle and the the side which was once the hypotenuse coincides with the x axis whereby the adjacent side's (cosine) value becomes equal to the radius of the unit circle which is 1 unit and the opposite side (sine) is no longer present so its value is 0.

Cos 60 = sin 30 Think about it for a second

@@diegojoaquinsanchezalatris6670 The prefix "co-" means "of the complimentary angle". Meaning cotrig(x) = trig(90deg-x), which is true for cosine, cotangent, and cosecant.

It turns out that calculators don't use the Taylor Series. In concept they could, but there are better methods that are more computationally efficient. Chebychev polynomials are a common alternative to use instead, as they converge a lot faster and get you more accuracy in fewer program steps. The Taylor series is a useful tool for introducing the concept of an infinite series, and has many applications within Calculus itself, but while it may seem to be a good idea as an algorithm for trig functions, there are better methods.

I know this is more than a year, but Eddie Woo was born in Malaysia. He is a chinese though. The family name, or surname Woo, hints that he is not from China, because in the Pin Yin system, there is no Woo, only Wu. China's Chinese must adhere to that system, while Chinese elsewhere just spell it as they would pronounce it.

@@dunnomuch3 Eddie Woo was born in Australia. His parents are are ethnically Chinese, and immigrated from Malaysia. So you were close, on your account of his background. Interesting observation about the spellings of surnames, it also explains why the surnames of Wang and Huang, often get respelled as Wong. The Pinyin system did a good job of capturing the essence of Chinese pronunciation, and trying to map it onto the prevailing norms of English letter pronunciation, as best as possible. Not an easy task, when even the homeland of the English language is so inconsistent. It's good that it was developed by a native Chinese speaker, as a native English speaker would probably miss about half the details trying to come up with the same system.
