Getting weird syntax on Casio classpad

Hi, when im trying to solve trig questions such as sin(x)=142/215 in interactive solve i get answers like x=360constn1+.......

does anyone know how to fix this? it's perfectly fine if i manually sin-1 to get the solution. also i get -numbers when using the sine rule on other questions which is odd.

is it on decimal? maybe something to do with degree/radian. Change some stuff at the bottom of the screen and see if that works.

Yeah... I use this calc as well.

"30 + 360constant(1)" is like saying: 30 + 360k, where k is a constant.
So I don't think you can 'fix it'.

I just drag it to the next line, and delete this constant.

There are an infinite amount of solutions so you have to put a restriction on it

Tried inputting
(for degrees)
or
(for radians)
at the end of the equation?

E.G. This should be what it looks like on the calculator
