Hi;

You mean the sum of any two sides of a triangle is greater than the third side.

The technique is called Hornerization and it is very common in numerical work. I can show you with examples...But it was only a first try perhaps there is something even better...

There is a standard move to begin with borrowed from numerical work.

Your expression can be reduced to.

Now you only need to know what i^2 is. The computation is trivial.

They do look a lot alike. This suggests that life here and life on Mars have a common ancestry.

I have only used a telescope a few times, saw Saturn.

A healthy imagination is the basis of all good science.

You have a telescope? What type is it? Is viewing good from Australia?

Or was the data from Mariner purposely falsified?

GS first reported them as being 10 to 20 miles wide. Unless, it was built by a super race such a construction would be very difficult.

Back in ancient times GS looked through his telescope and thought he saw a network of lines across the face of the Red Planet. He called them canali or something like that. People assumed he meant canal but in Italian canali means something else. Naturally a big stir was made of his Canals on Mars. Of course this was the cover story told to the unsuspecting, unknowing human masses...

So we have some good evidence of life on Mars...

I suppose you have heard of Giovanni Schiaparelli and his canals on Mars. Now, I did not him but I knew his son Big Joey Schiaparelli, he lived on my block. He told me that there were more pictures and evidence of life on Mars...
