## what is the right way to rearrange this ...

Maple

I have solution to system of equations that results (I assign it to) in:

```I2sol := -I*omega0*k*L*vin*1/(L^2*k^2*omega0^2 + R^2)
```

I then try to solve it for k by doing

```solve(I2sol = I2, k)
```

but that doesn't work.  What is the "right" Maple way to rearrange I2 such that the expression is the solution(s) for k?

## Error, missing operator or `;` in a Code...

Maple 2023

I can't figure out what Maple is complaining about with this error.  In fact, this is an exact copy/paste from another section in my document that runs fine.  This section, however, generates the error, "Error, missing operator `;`.

I appreciate any help!

## solve system of eqs in terms of other va...

Maple

How do I solve sol1 in terms of DC and T (and tau)?

Thank you

## simplify expresion by redefining express...

Maple

Say I have ,

sol1 := C*vout*vin/(Iout*L*k^2)

and I want to simplify this expression by replacing  with .

Then I need to simplify it further by noting that , and that , so that the answer is only in terms of , , and .

I tried `eval(sol1, vin/Iout = omega*Lm)` initially to step through the first substitution, but that just returned the same expression.

Thank you.

## how to simplify this?...

Maple

I can't figure how to simplify

V:= V1*R2/(s*C*R1*R2+R1_R2)

into

V = V1 *R2/(R1+R2)/(C*R1*R2*s/(R1+R2)+1)

with Maple

Basically, divide numerator and denominator by the s^0 coefficient.
