Concepts of dragon Calculus was invented independently by twain mathematicians, Issac overdue north of England and Gottfried Wilhelm Leibniz of Germany in the 1680s. Leibniz published his research in the journal ¡¥Acta Eruditorum¡¦ in 1684 and Newton ¡¥s treatise was published in ¡¥Principia Mathematica¡¦ in 1687. Calculus was mainly developed to solve two types of problems ¡V the closing of topazs to deviates, fig.1, and the calculation of bea, fig. 2, especially for irregular shapes. Both of these problems are closely related to the rate of change of continuous obligation and the total concept of calculus (also known as the ¡¥ frontier¡¦). The avocation shows what limit is and what are its applications. Fig.1 Given a exercise f(x) and a smudge P(x,y) on its graph, consider an equation of the argument of merchandise topaz to the graph at P. Fig.2 Given a function f(x), find the area between the graph o f f(x) and an separation [a,b] on the axis. In plane geometry, a statement is called a ¡§tangent¡¨ to the peck if it meets the circle at precisely unitary head, fig.3a. However, this definition is not correct for all kinds of scents and irregular shapes. In fig.3b, the line meets the dilute exactly once, yet it is not a tangent. Meanwhile in fig.3c, the line is a tangent, yet it meets the roll more than once.

Fig.3 For tangent that applies to curves other than circles as in fig.4a, point P on curve in the xy-plane and Q is any point on the curve different from P, the line through P and Q is the ¡¥secant¡¦ line (the secant line is a line that interce pts a curve at at least two points). If Q m! oves along the curve toward P, fig.4b., the secant line will circulate toward a ¡¥ pass¡¦ position. The line occupying this limiting position is considered...
