What's the difference between によって、次第、and 応じて?


Can someone please help me understand What is the difference between
によって、次第、and 応じて.

Thank you.




によって is spoken.

次第 is written very formal. I almost never get to use this when it's meaning is
+- that of によって but i use it all the time to describe a sequence (in sequence,
in order, in turn) particularly when I'm explaining CPUs to customers.

応じて written, not as formal. As well as 'depends on/depending on' it can also
mean in proportion to. so 「天気によって・・・」and 「天気に応じて・・・」are kinda like "depends on
the weather" and "weather appropriate"
