EQSolve is designed for those times when you need an answer to a wellknown equation quickly. Instead of having to remember the equation you39;re working on, rearranging the terms and then calculating each part separately with a normal calculator EQSolve does it for you. Simply select the equation you want to use, choose the variable to calculate, fill in the known variables and calculate the answer. No more pen and paper EQSolve includes 15 equations:Boyle39;s LawCharles39; LawCoulomb39;s LawEinstein39;s Equation of General RelativityHooke39;s LawHubble39;s LawIdeal Gas LawNewton39;s Law of GravitationNewton39;s Second LawOhm39;s LawPythagoras39; TheoremSnell39;s LawTrigonometry: cosineTrigonometry: sineTrigonometry: tan
