Usually only if the students opts for the advanced maths course/class. (Usually known as AP [advanced placement] in the US.)

In the US it varies by state and even city, but they did not teach calculus in high school in Philadelphia at least. Students could chose whether to take statistics or pre-calculus. Pre-calc was just basically trigonometry.

You learn something new every day.

Here in Finland the students are divided into "long" and "short" math. Both will learn basics of calculus and derivatives at least.

> I'm relatively sure that they teach basics derivatives, functions etc. in high school in every country.

You're wrong, they don't teach derivatives in the HS curriculum in Poland, even when you take advanced math in HS.

A picture of a function, its derivative and the notion, that one function shows the other's tangent's slopes, is all that's needed, that should fit in a high-school curriculum especially in physics.

But you are going to hear it anyway if you are going to study.

I didn't get taught derivatives, functions or summation in the UK at GCSE-level (16 year old).

I believe it was covered at A-level (18 year old) but you could only pick three or four subjects for A-Levels at the time, so you had to be selective about the subjects you picked depending on what you "want to be when you grow up", and what you thought you were good at so that you got good enough grades to go to a uni you liked.
