ISOL

Command

 

 

 

Type:

 

 

 

Description:

Isolate Variable Command: Returns an algebraic symb2 that rearranges symb1 to “isolate” the first

 

occurrence of variable global.

 

 

 

 

The result symb2 is an equation of the form global = expression. If global appears more than once,

 

then symb2 is effectively the right side of an equation obtained by rearranging and solving symb1 to

 

isolate the first occurrence of global on the left side of the equation.

 

 

If symb1 is an expression, it is treated as the left side of an equation symb1 = 0.

 

If global appears in the argument of a function within symb1, that function must be an analytic

 

function, that is, a function for which the calculator provides an inverse. Thus ISOL cannot solve

 

IP(x)=0 for x, since IP has no inverse.

 

 

 

ISOL is identical to SOLVE.
