I don't care enough to google that.

oh well
so lazy

abstractly put, calculus is not about looking at the state of something (like for example what is y = x² + 10 for x = 2), it's about looking at how it changes. the main concepts of calculus are differentation and integration:

- when differentiating a function you're not talking about the current value (the value of y at time x for example) but you're talking about how this value (y) is changing at time x, like if you have a parabole (like y = x² + w/e) and you're looking at the tip, y can be anything but y' (the change of y) is zero, in other words the slope of the graph is zero (it's not changing after all). for y = x² + c, the change of y or y' = 2x, so in this case the change of y at any value for x can be calculated by simply doubling x.

- integration is calculating the area between the graph and the x axis between certain values of x. this way you can also get the average value of y between certain values of x.

There's barely any maths in physics anyway unless you're doing it at university level.

CHEERIO!

There's no reason to study a function if you can't differentiate or integrate it. Those two things are so important if you're studying functions at all.

The daughter is kind of a nutter if she doesn't realize how much information you get with differentiating. Though it would be good to put that context in terms of position and speed. Helps understand shit.

not here. in my high school physics, we were manipulating differential equations to study basic RC circuits. Also basic radioactive decay.

wow, we were actually doing fun shit in physics back then. i got a 16/20 or something, which is considered a good grade in FR. only 11/20 in maths. fuck's sake. fucking fuck fucker.

I enjoyed Math, Physics, Chemistry, and to a lesser extent, Biology. Hated English/grammar classes...
