where the phenomenon being considered is inherently tied to direction and length from a center point. For instance‚ the examples above show how elementary polar equations suffice to define curves—such as the Archimedean spiral—whose equation in the Cartesian coordinate system would be much more intricate. Moreover‚ many physical systems—such as those concerned with bodies moving around a central point or with phenomena originating from a central point—are simpler and more intuitive to model using polar

Rene Descartes was born on March 31‚ 1596 in La Haye‚ France. His family connections lie south across the Creuse River in Poitou‚ where it was controlled by Huguenots. His father owned farms and houses in Chatellerault and Poitiers‚ and worked as a councillor in the Parlement of Brittany‚ passing on the rank of nobility to Descartes. At one-year-old‚ Descartes’s father left him in La Haye to re-marry ‚where he and his two other siblings were to be raised by his grandmother and then his great

the average and rms values of the periodic voltage or current waveforms‚ are computed? Some examples are also described there. In this lesson‚ the representation of sinusoidal (ac) voltage/current signals by a phasor is first explained. The polar/Cartesian (rectangular) form of phasor‚ as complex quantity‚ is described. Lastly‚ the algebra‚ involving the phasors (voltage/current)‚ is presented. Different mathematical operations – addition/subtraction and multiplication/division‚ on two or more phasors

discussion for decades and has yet to be fully resolved. As the principal advocate for dualism‚ Descartes states that as humans we are composed of two major substances: the mental and the physical which manage to exist side by side. Without a doubt‚ Cartesian Dualism was one of Descartes major contributions to the study of philosophy; idea with which I agree based on the following analysis. The fundamental choice between the mind-body problem and its contra argument is the existence of materialism and
