How to use postfix notation on latex for this

Question

$x=\frac{cos t}{1+sin^2 t}$ $y=\frac{sin t cos t}{1+sin^2t}$ ? I have done it like

cos t 1 sin 2 exp t add div

And

sin t cos t mul 1 sin 2 exp t add div

It gives no output at all .

Answer 1

I think you should consider writing t ahead of sin or cos ,in postfix notation argument variable comes first . It will be like

t cos 1 t sin 2 exp add div t sin t cos mul 1 t sin 2 exp add div Execute with this may this helps ! Thanks
