Sining up for tube on my tv - Office Equipment & Supplies

take you generator in and have the output tested for correct voltage and sine wave configuration
electronics rely on a perfect sine wave ac current as a manufactured sine wave affects electronic components such as capacitors, transistors and diodes
generator sets that run an alternator ( not an inverter ) have a pure sine wave and have less affect on electronics.
go google and type in search headings like ---sine wave, inverter sine wave, sine wave affects on electronics, alternator operation and inverter operations and then you may get a pointer as to why your inverter gen set is affecting your electronics

It is becaus the inverter erradiate EMI (Eletro Mechanical Interference) and the EMI is picked up by the TV antenna, try moving them a part as far away as you can from each other (the inverter and the TV antenna), there are also some filters you can pusches, but enven with all that stuff you could end up with EMI any way so don't spend to much,

Good luck!

The inverse sine and cosine equations mean "angle who's sine/cosine is:" The bounds of the arguments for these functions must be between 1 and -1, the maximum and minimum values of the sine and cosine functions, because no angle can have a sine or cosine that is greater than 1 or smaller than -1. Also it should be noted that the inverse sine/cosine function is not the same as 1/sine or 1/cosine, although the symbol makes it look like that.

That is correct: there is an error in your request. The range of the sine function spans the closed interval [-1, 1]. Thus the domain of the inverse sine function (the arc-sine) is the interval [-1,1]. However you are asking the calculator to calculate outside of the domain (7/2=3.5). If you are using the hyperbolic sine sinh, that is another matter.

The manual states when running on AC, it is the same sine wave ouptput that comes in. When running on DC, it is a modified sine wave.

While the domain of the sine function is the whole of the real line, it range spans the interval [-1,1]. In other words the sine of an arbitrary angle is imperatively somewhere in the closed interval [-1,1].
So when you want to find the arc sine corresponding to a given value of a sine function, you cannot give as argument to the arc sine [sin^-1] a value that lies outside the interval [-1,1].

For your case, the argument is 60 and it is outside the permitted domain [-1,1]. That is why the calculator protests by signaling a domain error.

pure sine wave will be the best option ,but note it is not very possible to get a pure sine wave type

sounds like a stop up ac drain tube you need to pull back carpet on wet side and look see wile car is running and ac is on
good luk hope you see some sines of water running

I would not do this, you really need a pure sine wave inverter to guarantee the safety of your CPAP machine. At the price they are selling this device it could not be pure sine wave. 150W pure sine wave would be $70-$100.

I'm not sure what the application is but I will offer the following. As a retired electronics engineer i can say for sure that a true sine wave does not have any harmonics in it. A modified sine wave will have some harmonics and other what I would call " trash content" depending on how it is modified.
