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
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
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
“Just to prove you are a member of MENSA…”
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.

Isn’t it 0? They are giving you the value of x so it’s a constant and not a variable.

You could just write it into an advanced calculator and then copy the answer. Ain’t that bad
