Write a shell script that calculates suumation of ( sqtr(sin(x)) ) for x =1 to n, where n is user input. I'm unable to evaluate sin(x) using any command tools in terminal.

Any reply will be highly obliged.

You can use bc (basic calculator) inside shell scripts. Sorry that I can't give you an example right now, but if you read the documentation it will be easy to implement:

bc manual

bc wikipedia
