'''Calculus''' (that is, the "infinitesimal calculus", see above) is the [[mathematics|mathematical]] subject that studies rates of change of functions.  There are two main branches of calculus—[[derivative|differential]] calculus,  and [[integral]] calculus.  There are subfields of these: single [[variable]] calculus, [[exterior calculus]], and multi [[variable]] calculus.

'''Calculus''' (that is, the "infinitesimal calculus", see above) is the [[mathematics|mathematical]] subject that studies rates of change of functions.  There are two main branches of calculus—[[Derivative (calculus)|differential]] calculus,  and [[integral]] calculus.  There are subfields of these: single [[variable]] calculus, [[exterior calculus]], and multi [[variable]] calculus.

Calculus has numerous applications in many fields, such as [[engineering]], [[physics]], [[chemistry]], [[biology]], and [[economics]].  Many physical properties can be explained and/or modeled through the use of calculus.
