Hate geometry 🙂

Also I have no idea what binomial theorem is yeah we have used it for derivation but i don't know it

[slate helm]

It is just an approximation like when (1+x)^n n is the power if here ‘x’ tends to zero we can write the whole thing as 1+nx

[halcyon magnet]

But the power isn't zero

[slate helm]

here u can replace x by any function if it tends to zero

[halcyon magnet]
