The action potential is a sudden positive shift in the cardiomyocyte's cellular membrane potential, termed depolarization. Depolarization not only initiates contraction within the affected cardiomyocyte (Described in Cardiac Excitation-Contraction Coupling), but also initiates depolarization of adjacent cardiomyocytes.
Polar Coordinates The coordinate system which depicts the points from the pole to the certain distance at a particular angle is known as âpolar coordinatesâ. The positive horizontal axis in which that particular angle rotates is named as âpolar axisâ.
The distance formula for Polar coordinates is P 1 P 2 = $\sqrt{r_{1}^{2}+r_{2}^{2}-2r_{1}r_{2}cos(\theta _{2}-\theta _{1})}$. where P 1 (r 1, Î¸ 1) and P 2 (r 2, Î¸ 2) are any two points on Polar plane. We can therefore conclude that the two planes were in violation of air traffic regulations.
