Type special symbols with Japanese input mode

Do you know that you can write this equation with your keyboard in Japanese input mode?

Δθ₀ = η × 1÷√(var(θ₀) + ε) × ∇(θ₀)

For example, θ can be input by しーた. ε can be input by いぷしろん, etc.

The exhaustive list of these symbols and the associated key combination can be found here:
