Mt. Takeda

I climbed Mt. Takeda in this morning.

When I began to climb Mt. Takeda, snow was falling.

So I did not expect the good view from the top.

First photo was  a view from the top at that time when  I had just arrived at the top .

It was so  snowy that I couldn't see Hiroshima City.

Fortunately,  the sky became blue 30 minutes later.

And  I felt  so happy, because my physical condition was recovered .

Torn muscle seemed to be also recovered.

Imaginery number calculation in Excel

I could find excel functions for the calculation of imaginery number on web.

Therefore my problem about the calculation was solved.

Those functions of complex, imsum, improduct,imsub,imdiv, imreal and imaginery are so useful.

I do not have to worry about the negative number in root .
