Some people (like me) may not ever need to remember how to solve a written out mathematical equation for years and years... Totally agree. Years after I learned the formula, when I started building things, the importance of the Pythagorean theorem became readily important. The light came back on. Trapezoids suck to build on.

Odin11 Posted August 11, 2013 #32 Share Posted August 11, 2013 Whats with all this hard math, lets do some easy math like what I had to do last year: Have fun! Age= [log (d/p +1)] [(λ / .693) * 2.3] Solve for age. d= daughter element = 0.0051 p= Parent isotope = 1.8 λ= half life = 4.5 x109 Link to comment Share on other sites More sharing options...
