For some reason I can't remember how to say "try to **_" or "have to (must)
_** " in Japanese. How can I say this? Any variations you can include would be
appreciated.

Try to ~

> ~ようとする (Does not give any information whether the action was actually
> carried out in entirety)
>
> ~てみる (Try for the sake of seeing the result, does **not** have negative
> implication as in "to try (unsuccessfully )" )

* * *

have to(must) ~

> ~なければならない
>
> ~なくては｛ならない・いけない｝
>
> ~ないといけない
>
> ~ねばならない

~なくては is often contracted to ~なくちゃ

~なければならない can also be contracted and have ならない elided to form "~なけりゃ" or
"~なきゃ" which is used informally.

Some other grammar for "have to" that was not yet mentioned:

### 〜ことになる

This means "it has been decided that 〜", but is often used as an indirect way
to say that you have to do something (even if it's been decided by you).

>   * 家族が大阪に引っ越すことになった → It's been decided that my family is moving to Osaka
> (= We have to move there).
>

## More Advanced:

### 〜ないわけにはいかない

### 〜ざるをえない

### 〜ないではいられない・〜ずにはいられない

These all basically mean "can't not do 〜" or "can't avoid doing 〜", although
the double-negative may slightly lessen the "activeness" of having to do it.

>   * この[推理小説]{すい・り・しょう・せつ}を終わりまで読まないではいられません。 → "I have to / I can't not read
> this suspense novel all the way to the end!"
>

Each one has its nuances of what types of situations in which it can be used,
whereas the "basic" ones in @Flaw's answers aren't limited (much, if at all).

## "Most Advanced" (mostly formal and/or written forms only. Not likely used
in conversation)

### 〜ないではすまない・〜ずにはすまない

### 〜ないではおかない・〜ずにはおかない

### 〜を禁【きん】じ得【え】ない

### 〜を余儀【よぎ】なくされる

It come to top of my mind for 'try to' ...してみる. やってみる....しようとする. ...を試みる.

and ...ねばならない. ...せざるを得ない. ...を余儀なくされる. for 'have to.' But the last one may
sound a bit antiquated today.
