That requires neither engineering-level math nor paper nor patience. All you need is the chain rule and some basic knowledge of sine and cosine:
The derivative of cos is -sin, but because of the 6x you get an extra factor 6. The sine function is periodic on 2pi, so sin(6*2pi + pi/2) = sin(pi/2) = 1. So the result is -36
My “advanced” maths course did (from what I could tell) the exact same as the basic one and we started calculus before the classes were split, the only issue would have been the notation and half the class not paying attention.
It’s quite easy after you learn engineering-level math. It would still require some paper and patience, but it’s not hard.
Only something around 5% of the people go there, but it’s a matter of going there, not being a genius.

It’s called engineering level math because engineers, physicists, and math majors are required to take Calculus.
Yes I took calculus in high school but it’s not required. No I don’t remember much of any of it because it was decades ago.
You also learned all the countries/capitals in Africa when you were in middle school. But I bet you can’t name them now without Google. Same thing.
