isolate variable
Personal:
How to isolate x in equation 1/√x=2*log((y*√x)0,8), on HP Prime? I looked in the groups and found no answers. Grateful Davidro

RE: isolate variable
The solution for x in this particular equation can't be expressed in terms of elementary functions. It needs the product logarithm (omega function), which the calc doesn't seem to have, so it won't be able to isolate x, unfortunately.
It can isolate y though: Code:

Lambert W (as an analytic function) has been missing ever since HP28C. – – VPN
