There’s 3 variables and 1 equation. This is unsolvable.

arcsin(nk-1) ?

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)

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.
i’m guessing they want you to solve for x by rearranging and then taking arcsin
Well the “student” and “grader” use the exact same pen and writing style…
Grading your own work is stupid.
Would only work if the numerator was 𝑛 + sin 𝑥
That’s for AP. Elementary logic let’s you divide willy nilly
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.
You should sin more, 'cos you’ll go to hell and there you can get a tan
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…
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.
x = arcsin (kn - 1)
I’ve solved it. There you go. I hope you use this solution for something good.
Solve for 1:
1 = kn - sin x
In regards to x, x=arcsin(kn+1), where kn is between -2 and 0
