Infinite Series Value

The value for an infinite series is what I yearn for.

We all know the value of infinite series of following 

Infinite geometric progression 

Sin(x)

Cos(x)

Log(x)

e^(i into theta)

Madhava-Leibniz pi series 

I think there are many many ways of calculating Infinite series values. In fact there are methods to calculate values of divergent series took.

And I know only Partial Sums method. 

Earning money for a 11th class or 12th class guy is more important than getting an education. This is what I believe.  Coming from Singhania employees, I can't help thinking otherwise. 

Have a nice day!!
