| Feb 11, 2019 at 14:53 | comment | added | Leon Rai | Well, it was a typo then. As I said I don't know how to go from $z_k$ to $H_{k+1}$, I found some articles and that brought me this far. I am not sure how to explain what I don't know how to explain. Thanks. | |

If you're asking if it's the correct way then you probably suspect it's not the correct answer. If that's the case then why do you think it's not right? How did you get from $z_k$ to $H_{k+1}$? $z_k$ is a singular value, but you have a comma in the $H_{k+1}$ expression; did you mean for that to be an arctangent, too, or is the comma a typo? As I wrote earlier, it's hard to point out where you're going wrong if you don't step us through your solution. | |

| Feb 11, 2019 at 14:28 | comment | added | Leon Rai | I feel like it is not right to directly ask about your problem but rather ask a general question which others can benefit too, therefore I tend to ask a more theoretical question. I see now, the more specific the problem, the better people can help. Thank you again. Hope my edits will make more sense now. | |

| Feb 11, 2019 at 14:05 | comment | added | Chuck♦ | @LeonRai - Looks better, but please try to show how you would approach the problem and why you think you're doing it incorrectly. Your prior edit made it seem like linearizing the process equations was not a problem, so what makes these equations different? Even a little bit of information here is useful, like, "I don't know how to linearize inverse trig functions," or, "I linearized the arctangent, but I get X when I expected to get Y for an input of <inputs>." Hopefully you can see how these two different statements can lead to very different answers; they cover different problems entirely. | |
