Maybe you make a table:<\/p>\n<style type=\"text\/css\">\ntd {text-align:center;\nborder-style:solid; border-width:1px;border-color:gray\n}\n<\/style>\n<table style=\"width:22%; display:block;margin:auto;border-style:none\">\n<tr>\n<td>a<\/td>\n<td>b<\/td>\n<td>c<\/td>\n<\/tr>\n<tr>\n<td>1<\/td>\n<td>2<\/td>\n<td>&#8730;5<\/td>\n<\/tr>\n<tr>\n<td>2<\/td>\n<td>2<\/td>\n<td>&#8730;8<\/td>\n<\/td>\n<\/tr>\n<td>3<\/td>\n<td>4<\/td>\n<td>5<\/td>\n<\/tr>\n<tr>\n<td colspan=\"3\">&#8230;&#8230;&#8230;.<\/td>\n<\/tr>\n<\/table>\n<p><\/p>\n<p>Of course, you&#8217;re probably really interested in sets of values for which c is a whole number:<\/p>\n<p>c=&#8730;(a^2+b^2), c any whole number<\/p>\n<p>Using the Sharp El-520W, there&#8217;s a convenient way to find such sets of numbers.  Sharp calls it <span style=\"font-variant:small-caps\">simulation calculation<\/span>.  Here is how to enter the formula on the EL-520W:<\/p>\n<ol>\n<li>Press <span style=\"font-family:monospace\">MODE<\/span> then <span style=\"font-family:monospace\">0<\/span><\/li>\n<li>Press <span style=\"font-family:monospace;color:white;background-color:orange\">2nd F<\/span> then x^2 then (   <\/li>\n<li>Press <span style=\"font-family:monospace; color:green\">ALPHA<\/span>, then <span style=\"font-family:monospace\">CNST<\/span>, then the x^2 key.  You&#8217;ll see A^2 on the screen.<\/li>\n<li>Continue entering the formula: <span style=\"font-family:monospace\">+<\/span> <span style=\"font-family:monospace; color:green\">ALPHA<\/span> then the y^x key, then x^2, then ) =<\/li>\n<li>Now, press <span style=\"font-family:monospace;color:white;background-color:orange\">2nd F<\/span> <span style=\"font-family:monospace\">MATH<\/span>.  Your formula will appear, with A flashing.  You can key in the value you want for A, then press =, at which time B will start flashing.  You can now key in the desired B value, then press =.  The value of &#8730;(A^2 + B^2) will appear.  For instance, if you key in 6 for A and 7 for B, you&#8217;ll get 9.219544457 output.\n<\/li>\n<\/ol>\n<p>By trying various values of A and B, one can conveniently discover which C values are whole numbers &#8211; in this case, thanks to the Sharp EL-520W.<\/p>\n<p>HTH:)<\/p>\n<p>Sources:<\/p>\n<p>Sharp EL-520W Operation Manual.<\/p>\n<p><a href=\"http:\/\/www.w3schools.com\/css\/\">w3schools<\/a><\/p>\n<p>Jack of <a href=\"https:\/\/www.oracletutoring.ca\">Oracle Tutoring by Jack and Diane,<\/a> Campbell River, BC.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The tutor shows another feature of the Sharp EL-520W: simulation calculation, aka repetitive calculations with a formula.
