Steigung einer KurveDie Steigung der Kurve in dem Punkt A wird durch die Steigung der dort anliegenden Tangente T beschrieben. Rein rechnerisch ergibtsich die Steigung durch die Konstruktion des Steigungsdreiecks ABC. Sie entspricht dem Quotienten aus der Strecke k und derStrecke h.© Microsoft Corporation.

of the catalyst, including selectivity for the case of more complex catalytic pathways. Figure 2B suggests the local regeneration of deactivated areas as one possible starting point for such a design. In the case of island- forming reactants, for which the reaction oc- curs at the perimeter of these islands (34,35), the generation of additional boundaries should enhance reaction rates. What are good feedback laws for these objectives, and how can they be implemented? Hierarchical con- trol schem...

Automobile.
Electric motors have been used to power automobiles since the late 1800s. Electric power supplied by batteries runs the motor, which rotates a driveshaft, the shaftthat transmits engine power to the axles. Commercial electric car models for specialized purposes were available in the 1980s. General Motors Corporation introduced amass-production all-electric car in the mid-1990s. Automobiles that combine two or more types of engines are called hybrids. A typical hybrid is an electric motor with ba...

Limits
This graph, which charts the function f(x)=1x, shows that the value of the function approaches zero as x becomes larger
and larger.
DerivativesThe derivative of a function at a given point is equal to the slope of the line that is tangent to the function at that givenpoint. In this example, the derivative of f(x) at x0 is defined as the slope of AB in the limit of h going to zero. As hbecomes increasingly smaller, B moves along the curve towards A, and AB increasingly approximates T, the tangent to thecurve at x0.© Microsoft Corporation. All Rights Reserved.

INTRODUCTION
Physics, major science, dealing with the fundamental constituents of the universe, the forces they exert on one another, and the results produced by these forces.
Starting about 1665, at the age of 23, Newton enunciated the principles of mechanics, formulated the law of universal gravitation, separated white light into colors,proposed a theory for the propagation of light, and invented differential and integral calculus. Newton's contributions covered an enormous range of naturalphenomena: He was thus able to show that not only Kepler's laws of planetary motion but also Galileo's discoveries of falling bodies follow a combination of his ownsecond law of m...
