If c > 0 in the equation ax + by + c = 0 of the straight line and the given point and the origin are on the same side of the given straight line, then the required length of the perpendicular is positive and if the given point and the origin are on the op..

In an Earth environment, electromagnetic waves propagate in ways that depend not only on their own properties but also on those of the environment itself. Since the various methods of propagation depend largely on frequency therefore the complete electromagnetic spectrum is now shown for..

In a frequency distribution, the mid-value of each class is obtained. Then on the graph paper, the frequency is plotted against the corresponding mid-value. These points are joined by straight lines. These straight lines may be extended in both directio..

When two straight lines meet at a common point, they form an angl..
