In other words, do they appreciate mathematical situations where that form is needed, and have assignments where that form (and not other forms) are necessary for further steps? <br /><br />For example, they may need to work with vectors with √3 unit lengths, or prove that the answer is irrational (which the calculator can't do).MariaDhttps://www.blogger.com/profile/00769513929584082597noreply@blogger.com
