Question

Can anybody help me with this equation please?

y = 1E-09x3 - 6E-06x2 + 0.0089x + 1.2673

Basically I want to rewrite it simply, without letters inside, but with mathematical symbols and abbreviations (e.g "exp" etc).

Any ideas please?

Answer 1

The result will be something similar to this: Y=34/[1+8.254* exp(-0.2097*X)]. Thank you

Answer 2

Is the problem that you don't understand what the "E" means in this context? In many computer outputs, the "E" is used to represent scientific notation, so in general, "xxxEyyy" means
\[xxx \times10^{yyy}\]
so the first term is
\[1\times10^{-9}\times3\]
but again you wrote "x3" so I don't know whether that means "times 3" or you really meant "times x-cubed," or
\[1\times10^{-9}x ^{3}\]
I suspect the latter, since you have "x3"..."x2"..."x" which makes this a polynomial where the numeric coefficients are using scientific notation (the "E" format).
