I need to find the value of
n but I get an error. I used this:
Solve[ 4*ArcSin[Sqrt[(4 - (n^2))/(3*(n^2))]] - 2*ArcSin[Sqrt[(4 - (n^2))/3]] == 20.2826, n ]
But I get this error:
Solve::inex: Solve was unable to solve the system with inexact coefficients or the system obtained by direct rationalization of inexact numbers present in the system. Since many of the methods used by Solve require exact input, providing Solve with an exact version of the system may help.
Please, help me to get the value of
n. I know that the value of n should be about 1 or 2.
