I refuse to ever major in anything math-related no matter how much my parents push me. Sorry to hear that.
Caclulus. You take a formula, such as y= x^4-6x^2-5x-7 and turn it into the derivative. In this case, I would turn it into dy/ dx= 4x^3 - 12x^2 -5 From there I can find gradient, x co-ords, y co-ord, etc. Watch me kill the chat with maths
Interesting. Now based on that: Why don't we just see what happens when i put a jawbreaker in a microwave on high?
Seems complicated at first, but it gets easier with practice. Differentiation is used to find the gradient of a point on the graph whilst integration (the opposite) can be used to find the area under the graph. It sounds useless but it has some practical applications in physics. I suppose that you don't want to be bored by a lesson on calculus though, so I'll stop.
