To answer your question without being a dickhead: The given x indicates the point on the curve you need to find the slope at. In other words, find the derivative and then evaluate that function at the given x.
It is a partial derivative. Apparently you haven’t taken Calc III. I figured that would be basic math for most people. It is a shock to me that a person studying to be a nurse doesn’t need a degree in math.
Never mind. I misunderstood your question. Also I was joking about the calc III is basic part
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 been nearly 35 years since I did uni level calc and I’ve not really used in the the years since - fucked if I could figure it out without a lot of <insert search engine of choice> foo these days
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.
