Role of calculus in marine sciences

Calculus has two parts: differential and integral calculus. Historically, differential calculus was concerned with finding lines tangent to curves and with calculating extrema (i.e., maxima and minima) of curves. Integral calculus has its roots in attempting to determine the areas of regions bounded by curves or in finding the volumes of solids. The two parts of calculus are closely related: The basic operation of one can be considered the inverse of the other. This result is known as the fundamental theorem of calculus and goes back to Newton and Leibniz, who were the first to understand its meaning and to put it to use in solving difficult problem
