Abstract A complex number is a number that can be written in the form of a+bi where a and b are real numbers and i is the value of the square root of negative one. In the form a + bi‚ a is considered the real part and the bi is considered the imaginary part. The goal of this project is show how the use of complex numbers originates in the history of mathematics. Introduction Complex numbers are very important component of mathematics. They enable us to solve any polynomial equation of degree

Genes and Genetics 1. 2. each chromosome exists as two genetically identical chromatids attached to their centromere. Each chromosome appears as two chromatids attached to a centromere. In the first meiotic division chromosomes align in homologous pairs. Points of contact form between members of the same homologous pair. The points of contact or crossing over between members of a homologous pair are the chiasmata. 3. The homologous pairs move to the equator of the cell. Equal lengths of the

OPA Circle Style The three circles; O‚ P and A intersect to create an interesting investigation regarding circles. Since this is a Calculus course‚ the investigation does have to deal with Derivatives. The most important and the focus of this portfolio is the line segment‚ OP’. Using the given diagram above‚ this investigation consists of finding the general equation for discovering OP’. The values that are given are that r‚ is the radius of C1 and C2. OP and AP are the radii of C3. This information

Math SL Investigation Type 2 Stellar Numbers This is an investigation about stellar numbers‚ it involves geometric shapes which form special number patterns. The simplest of these is that of the square numbers (1‚ 4‚ 9‚ 16‚ 25 etc…) The diagram below shows the stellar triangular numbers until the 6th triangle. The next three numbers after T5 would be: 21‚ 28‚ and 36. A general statement for nth triangular numbers in terms of n is: The 6-stellar star‚ where there are 6 vertices‚ has

Release of energy. Breaking of bonds : Gain / absorption of energy. 6.2 Calculation of enthalpy changes 6.2.1 Change in energy = mass x specific heat capacity x change in temperature (E = m x C x ΔT) 6.2.2 Enthalpy changes (ΔH) are related to the number of mols in the reaction. If all the coefficients are doubled‚ then the value of ΔH will be doubled. Attention must be paid to limiting reagents though‚ because enthalpy changes depend on the amount of reactants reacted (extensive property of enthalpy)
