There are ways to express numbers and number system.

One is Riemann zeta functions.

Second is #PythaShastri p(k) / p(k+1). This expresses the hope that there will be another prime.

Third is #PythaShastri p(k)-1,p(k),p(k)+1. This gives a hope of next number.

Madhava of Sangamagrama was of the third variety. Hope of next number.

If you subtract the first from third you get second. That is the small trick he played and got series of pi and theta in terms of tans.

He wrote in cryptic Sanskrit with words difficult to understand.

I did a even number jumps but then I got the original series .

Also I believe in explaining and getting acceptance.

Madhava of Sangamagrama caused much disgrace to himself by doing the theta and tan equations. He should have realised a trick is good only once. Shameful Madhava goes on and on for an angle can be equated to tan only for small angles.

He could never have got the sines and cosines functions without explaining e series. No wonder Kerala astronomy academy has been reduced to dust.

Euler was of course different from all of us and made genius methods.
