Total final uses  $$=\sum_{j=n_2+3+2}^{n_2+3+21}Y_{i,j}$$ or all $$i=1,\ldots,n_1+1$$
To copy the equation back into MS Word, right-click the equation above and choose "Show Math As > TeX Commands".

In Word, right-click the arrow to the right of the equation to toggle between Linear (script) and Professional (display)

Sloppy circle:
y= (1-x^2)^0.5, y=x, y=-x, y= -((1-x^2)^0.5)

Sloppy infinity (default):
y=(x * (1-x^2))^0.5, y=-((x * (1-x^2))^0.5), y=((-x * (1-x^2))^0.5), y=-((-x * (1-x^2))^0.5)
