Recently got hired as adjunct and was given Real Analysis to which I was more than excited to lecture.

However in the first week when I tried to explain how the set [0,1] contains and infinite amount of real numbers I was immediately met with skepticism by a student.

He proceeded to press me on the matter and since I was new I became visibly anxious, slurring my words which was further intensified when I deduced that the set was not just infinite, but uncountably infinite to which I was met with skepticism as another student joined in pressing me.

At this point I was visibly uncomfortable as it is a very bad sign to be doubted not just once but in a consecutive matter to the entire class.

The final straw was when I, using the same reasoning arrived at (0,1) having the same cardinality as the entirely of R to which a different student proceeded to walk out of the classroom.

By the end, I was sweating bullets and I am now dreading coming back to lecture on monday. How do new adjuncts deal with this type of anxiety ? is it normal to be pressed this much at first ? if my students are now skeptical is there anything I can do to win their trust back?

If the anxiety Is preventing me from effectively lecturing will I have to resign?

I am absolutely terrified as I have to touch on cauchy sequences and equivalence classes very soon and I already know what their reaction will be like.

I think I will have to talk to the chair of the department for possible options

When i watch some MIT lectures on YT and see some those people teaching there that have worked in alot if cool places, are experts in the field, got phds and shit from top unis, have experience researching secret stuff at companies or the armed forces, i feel a bit inferior that I'm just doing a random econ uni and procrastinating, also the young people that got to go there and do all those peculiar projects like building rockets.

Hi /sci/ so I'm writing a midterm in my circuits class in a couple weeks. My professor will let us use any technology and notes we want. What should I invest my time in learning? So far I'm thinking:
> HP Prime
> Manually by hand with a basic scientific calc
> ltspice
>matlab programs
It's the first circuits class so it won't be anything too complex but engineering midterms are famous for being time intensive as you know so I want to be as fast as possible.

Can't wrap my head around it, is it the formula that where you plug in x(t) or is it something more complex?

Why is it called Pascal's triangle if it was discovered previously by other people? Why is this such a common occurrence in mathematics? Where a concept is named after a European who rediscovered something that was already known by older civilizations?
>The elements of Pascal’s triangle are called the binomial coefficients, because the
nth row consists of the coefficients of the terms in the expansion of (x + y)
n
.This pattern for computing the coefficients appeared in Blaise Pascal’s 1653 seminal work on
probability theory, Traité du triangle arithmétique. According to Knuth (1973), the same
papttern appears in the Szu-yuen Yü-chien (“
The Precious Mirror of the Four Elements”),
published by the Chinese mathematician Chu Shih-chieh in 1303, in the works of the
twelth-century Persian poet and mathematician Omar Khayyam, and in the works of
the twelthh-century Hindu mathematician Bháscara Áchárya

Literally all the technology has advanced leaps and bounds since then it should be fucking easy.

How long until we have FTL craft?
