Solve for a
c+=++sqrt+%28a%5E2+%2B+b%5E2%29..........raise both sides to the second power
c%5E2+=++%28sqrt+%28a%5E2+%2B+b%5E2%29%29%5E2..........
c%5E2+=++a%5E2+%2B+b%5E2..........move b%5E2 to the left
c%5E2+-+b%5E2=++a%5E2+..........
or
a%5E2+=+c%5E2+-+b%5E2+..........

then:
a+=+sqrt%28c%5E2+-+b%5E2%29
