Solve for 1:
1 = kn - sin x
x = arcsin (kn - 1)
I’ve solved it. There you go. I hope you use this solution for something good.
WTF bro, There is 3 variables.
Wait? NVM Wait?
Today I did Calculus for 6 hour straight. So, don’t mind me I am just tired.
I want to believe this is real, but I’m having trouble deciphering how one would “solve” this equation given no variable is referenced outside of the question and k is already isolated and terms simplified.
Well the “student” and “grader” use the exact same pen and writing style…
i’m guessing they want you to solve for x by rearranging and then taking arcsin
There’s 3 variables and 1 equation. This is unsolvable.
You can reform the term until it reads x =
arcsin(nk-1) ?
Looks correct. However it’s only valid for n ≠ 0.
B
if n = 0 then k = ∞ and just about any value of x works in this case. however x = arcsin(nk -1) still doesn’t work since 0 * ∞ is not defined. so i think the B grade is fair.
(this is all assuming we’re working on the riemann sphere)

Grading your own work is stupid.
I cannot actually believe that back in the day, I understood what these were.
so you don’t understand sin anymore? or division?
I don’t sin anymore.
I haven’t had to do anything with sin, cos or tan in over 20 years and even back then it’s a miracle I managed to pass my advanced math course considering I never understood what they were because it was so badly explained to us…
Would only work if the numerator was 𝑛 + sin 𝑥
That’s for AP. Elementary logic let’s you divide willy nilly
