Essays on Sine

1. The Sine and Cosine graphs are 'complementary', which means that the expression sin2 x + cos2 x = 1 is realized. Therefore, when sin (x) = 1, in that point cos(x) = 0, and vice versa. The same situation is observed when the functions take -1 and 0 values. Therefore, if Sine and Cosine are plotted on the same graphs, they look the same, but as if Cosine function is shifted by pi/2 comparing to Sine. Since Tangent function is obtained as sin x / cos x, then the point x = it should not reach the x-points pi/2, 3pi/2, etc. The ...

The sine is the ratio of the opposite leg of the right triangle to its hypotenuse. Let’s imagine that we have the Cartesian coordinate system and a circumference with the same center and radius R. Every angle can be depicted as a rotation operation from the positive x-axis to some interval that joins together the center of the Cartesian coordinate system and some point of the circumference. The length of this interval is equal to the radius and can be depicted as the hypotenuse of the right triangle. The adjacent leg of the triangle belongs to the x-axis, ...

Most of the black writings have been based on historical circumstances that mainly condition the black’s race consciousness. Many have been focusing mostly on fictional, prose and dramatic genres and less have shown interest in focusing on the post-colonial treatment in modern African poetry. Night of Sine by Leopold Senghor has taken the route of post-colonial literature. Senghor was one of the African port that made major contributions to the Negritude movement that was started by the French-speaking intellectuals who were black. These philosophers accepted the facts that one was black, and this came with its history. Leopold ...

Introduction

Numerous electrical applications require an inverter, which converts Direct Current (DC) to Alternating Current (AC) power. Some of these applications require the stepping down of voltage levels when realizing this conversion, which signifies that the input DC power is greater than the AC power. Conversely, certain applications require the opposite: to step up voltage when performing the power conversion, which means that the input DC power is lower than the AC power. These requirements can be met through the use of Voltage Source Inverters and Current Source Inverters, respectively. However, some particular applications require to step down voltage for ...

Introduction

Taxicab geometry is a better idealized model for urban geography as compared to Euclidean geometry. This is very applicable in urban planning where distances within the roads are divided within rigid blocks and the shortest distance cannot be the hypotenuse. This is very helpful in establishing the shortest distance between any two points. ( Surhome, Timpledon & Susan). Geometry can be traced back over 2000 years. This is solely refers to Euclidean geometry introduced by Euclid. A German mathematician Hermann Miknowski proposed taxicab geometry. He had the proposition that distances in taxicab geometry is different than in Euclidean geometry. His ...
