Hi can i change the subject of a letter in a formula? For example, V = 4/3πR^3 How would I, using the calculator in formula typing mode , make R the subject in this formula? I have a Casio fx5800p

Hello teslacoil and welcome to UCF! You should introduce yourself.

I am not sure that the calculator can do that for you, but it isn't very difficult to do it yourself.

sorry İ did introduced right now

No i just wanted to know the capacity of the device.There are other equations that the solution is given and they ask you to find the variable in reverse

like E=((100.l.P)/(kqV^2)).f(w):f(w)=(1+12q) E=10 q=? I looked up the manual or tried to use break function but no way it seemed .Course it can be solved via casio
basic programming

Ah, ok. Yeah, I'm not sure that any casio calculators can do that.
