Convexity formula

Are we expected to memorize the Convexity formula-or is it normally given… any 1 saw questions requesting to calculating it? Thanks

I don’t think any formulas are given on the exam. IIRC they only give you the probability tables (z scores etc). It’s really not that hard. Similar to duration, but with a quadratic term in it.

by given i meant as a given value like 70…

That’s not a formula
