ETIMOLOGY
ThewordcalculuscomesfromLatinandmeans«asmallpebbleorstoneusedforcounting»
BRIEFHISTORY
Moderncalculuswasdevelopedin17th-

Whatdoescalculusstudy?
Calculusisthestudyofthechangeanditstudieschangebystudyingistantaneouschange(overatinyintervaloftime).

Twoproblems
1) Findtheinstantaneousvelocitybyknowingthefunctionposition(calledmoreingeneralthederivativeofthefunction)
DIFFERENTIALCALCULUS
2)Findthepositionbyknowingtheistantaneousvelocityatalltime(ormoreingeneral,Oindthefunctionbyknowingitsderivative).
