functions
My HP 48G/GX has a function to solve for a variable in symbolic, for example: C=2*Pi*r*h, solving for "r". The HP 48G/GX returns the formula for r=C/2*Pi*h. I realize that this is a simple formula to solve for the variable r or h, but in complicated formulas the solve for a variable function in
symbolic would be appreciated. Does the HP Prime Graphing Calculator has a function like that? I went through the "Catalog" menu, the app menus, but could not find one.

RE: functions
Have you tried: solve('C = (2*π*r*h)',r) ?

RE: functions
[CAS] MODE (Symbolic operation)
solve( C = 2*π*r*h, r, '=' ) [enter] r = C/(2*h*π) HOME MOD (Numerical operation) solve(C = (2*π*r*h),r,'=') [enter] error LO SUFICIENTEMENTE BUENO ES ENEMIGO DE LA EXCELENCIA.

RE: functions
Hi!, rolfjg8 :
Per example, if you needed calculate, the surface area of cylinder, as ... C=2*pi*R*(H+R) =~ 6.28319*R*(H+R) Assuming = Base radius "R" and height "H" Then in the HP PRIME, you can in CAS MODE and Apps Solve ... Write in Solve Symbolic View ... C=6.28319*R*(H+R) Press button Num and see ... C: R: H: Example ... R= 5 H=25 Put the bar in C, and press Solve. The result, is ... 942.4785 If needed find the radius "R", the formulae, is ... R=C/6.28319*(H+R)

RE: functions
If you want to do symbolic manipulations, press the CAS key!
