# Bhāskara

Provides Bhaskara I's sine approximation formula

```julia

bsin(θ) = 16(π-θ)θ / (5π^2 - 4(π-θ)θ)      # error < 0.002, θ ∈ [0,π]

```

There is also `b2sin(θ)` for `θ ∈ [-π,π]`, and `Bhaskara.sin(θ)` for `θ ∈ 𝐑`,

by inserting appropriate `mod(,2π)` and `sign()*abs()` bits. 

Similarly `bcos(θ)` is for `θ ∈ [-π/2,π/2]`, and `Bhaskara.cos(θ)` for all `θ ∈ 𝐑`.
