eruonna 🏳️‍⚧️<p>Math-y people of fedi, how do I get more math into my life, as a person who dropped out of a PhD about 15 years ago and now works a software job she doesn't much care for? <a href="https://chaosfem.tw/tags/math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>math</span></a> <a href="https://chaosfem.tw/tags/maths" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>maths</span></a> <a href="https://chaosfem.tw/tags/mathematics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>mathematics</span></a></p>
Paysages Mathématiques<p>"The idea of math is to look for similarities between things so that you only need one "recipe" for many different situations. The key is that when you ignore some details, the situations become easier to understand, and you can fill in the variables later. This is the process of abstraction." – Eugenia Cheng<br><a href="https://mathstodon.xyz/tags/quote" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>quote</span></a> <a href="https://mathstodon.xyz/tags/mathematics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>mathematics</span></a> <a href="https://mathstodon.xyz/tags/math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>math</span></a> <a href="https://mathstodon.xyz/tags/maths" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>maths</span></a></p>

#Math #Maths #Mathematics I get maths students coming to me in their last year of high school not having learnt the main reason we use radians rather than degrees

Essentially, calculus.

E.g. the derivative of a trig function where the variable is in radians, is simpler/cleaner than in degrees, for example:

If x is in radians then
d/dx (sin x) = cos x

In degrees:
d/dx (sin x) = (pi/180) cos x

The extra factor of (pi/180) makes things messy.
