Hi, I'm a new user of smath and have come across an issue when I try to calculate the sqrt for a range of values, I just get a message saying that smath is unable to calculate. Attached is an image of a simple sheet showing what I am trying to achieve, ideally I wouldn't have interim values for f listed

Any help gratefully received.

If you want to use a function (in this case "sqrt" ) for each of the vector elements, you must use the SpecialFunction "vectorize". another possibility is to run a "for" loop.

Simply like this.
