Returns the equivalent y-coordinate of the
(r,θ) pair.

either a degree, radian or gradian angle,
according to the current angle mode. If the
argument is an expression, you can use°,

PassErr
Catalog >
PassErr
Passes an error to the next level.
If system variable errCode is zero, PassErr
does not do anything.
The Else clause of the Try...Else...EndTry
block should use ClrErr or PassErr. If the
error is to be processed or ignored, use
ClrErr. If what to do with the error is not
known, use PassErr to send it to the next
error handler. If there are no more pending
Try...Else...EndTry error handlers, the error
dialog box will be displayed as normal.
For an example of PassErr, See Example 2
under the Try command, page 187.
