Where can they help solve this problem?

Question

Visual Basic

It has been a school for a long time. there was no mathematics for a long time. I ask those who know to direct me what to look for in Google in order to understand how this is solved. maybe someone could help with a bottle of beer.
It is further complicated by the fact that you need to do this in Visual Basic

Answer 1

As you rightly noted, there are two cycles.
The first for loop starts at 2 and iterates up to 6. Inside that loop, there is another for loop that starts at 1 and iterates up to 7. That's it.
All other functions (logarithm, sine, etc.) are in VB itself.
At the very beginning, you create a variable z and assign it the value 1.32.

Answer 2

If this needs to be done in VB, then knowledge of mathematics is not needed here at all.
There will be 2 loops (one nested) and that's it. Stupidly you substitute numbers instead of x, y, z and consider values.
