variables which would take only integer values.These equations are famously known as “DIOPHANTINE EQUATION”‚named due to Diophantus.The simplest type of Diophantine equations that we shall consider is the Linear Diophantine equations in two variables: ax+by=c‚ where a‚b‚c are integers and a‚b are not both zero. We also have many kinds of Diophantine equations where our main goal is to find out its solutions in the set of integers.Interestingly we can see some good theoretical discussion in Euclid’s

Barely being able to open it as the wind pushed against him‚ he shoved his axe so the door would stay open for his brothers. The next brother to reach the cabin was Drake. Just like Jake he barely could open the door. As he got inside‚ he pulled the ax out of the doorway‚ thinking everyone was inside. He was overcome with the temperature difference that he forgot to notice one thing. Looking around concerned and worried‚ “Where’s Bobby?” Drake asked with the look of fear on his face. Jake also

The eye of a hurricane passes over New Orleans in a direction 60.0° north of west with a speed of 41.0 km/hr. Three hours later‚ the hurricane suddenly shifts due north‚ and its speed slows to 25.0 km/hr. How far from New Orleans is the hurricane 4.50 hours after it passes over the city? v1 = 41.0km/hr(cos30°‚ sin30°) = (35.5‚ 20.5) km/hr v2 = (0‚ 25.0)km/hr → D = v1×3hrs + v2 × 1.5hrs =Answer (105.9‚ 99) km A ship which can move at the velocity of v0 = (12‚ 6) m/s (x-axis: the West to the
