Upgrade succeeded, please use linear mode after repair.
There are eight modes, which can be freely converted or eqn can be used. The biggest disadvantage is that it crashes when calculating in mathematical mode, and no method of guiding and maintaining has been found yet. In addition, sin in the log (replaced by ln(6 mode appears).
