I've seen pretty bright seeming UK university applicants able to do whatever you ask them but then completely shit the bed when you ask them to differentiate e^y with respect to y rather than e^x with respect to x.
- ithinkso 5y agoEven worse, I've seen a lot of people that where convinced the derivative of f(x)=e^7 is e^7
- londons_explore 5y agoThat would trick me too... Exam questions never ask 'trick' questions like that where the answer is zero/infinity/undefined.
- Rompect 5y agoI genuinely don't know whether the trick of that question is swapping the `e^x` with `e^y`, so just renaming a variable – or is `y` a function?
- eigenket 5y agoYou're differentiating the function f(y) = e^y with respect to y
