As a starting point of attention by the Ministry of Education represented by the General Directorate of Curricula to develop the curricula in general and specially of maths in order to go along with the technological scientific . This book is part of the of the project to diversify education for sixth – graders / (Biology Branch). The book consists of six chapters: The first chapter is (Complex Numbers) which contains: Find the roots and their properties ,Solving second –order equation .in complex number , polar coordinates , Modulus and Argument of complex numbers . The second chapter is (Conic Sections) which contains: The standard equation .for Parabola , Ellipse and Hyperbola, and eccentricity of each them. The third chapter is (Application of Di�erentiation) which contains: Higher-order derivatives, Related Rates. Rolle›s and Mean value theorem ,the derivative test for increasing and decreasing for a function, local Max and Min. Concavity and inflection opint, the second derivative test for Local Max. and Min graphing functions and optimization (Max ,Min) problems. The fourth chapter is ( Integration )which contains: Integration and it find integration of Algebraic, Logarithmic , Exponential and Circular functions find the area between x-axis and the curve , and the area between two curves ,find the volume of revolution . The fi�h chapter is (Ordinary Di�erential Equation) with contains: find (Degree, Order and Solution) and solving equation by separation of variable and by homogenous equations. The sixth chapter is ( Space Geometry ) which contains: Dihderd angle and perpendicular planes ,and Orthogonal Projection on plane . We hope God help us to serve our country and our sons Authors 3 (16) : 6 - 42 (18) : 43 - 73 (48) : 74 - 133 (26) : 134 - 175 (13) : 176 - 197 (9) : 198 - 214 4 ..................... 6 ..................... ..................... ..................... ..................... 11 16 22 25 ..................... 29 ..................... 32 ..................... 37 5 6 w = { 0 , 1 , 2 , 3 , . . .} Whole Numbers W = {0 , 1 , 2 , . . . } 7 Note Complex Number 8 9 Equality EqualityofofComplex ComplexNumbers Numbers 10 Addition of Complex Numbers 11 z : c + z = z+ c = 0 12 z = -c 13 1-4 Multiplying Complex Numbers Find the result of the following 14 15 Complex Number Conjugate 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 .................. 44 .................. 45 .................. 56 .................. 67 43 2 - 1 Conic Sections 2-1 In this section we give geometric definitions of parabolas, ellipses, and hyperbol and derive their standard equations. They are called conic sections. because its consist from intersecting a right circular cone. with a plane as shown in Figure 2 - 1 parabola Ellipse Figure 2 - 1 Hyperbol 44 2-1 2-2 45 46 47 48 49 50 51 52 53 54 55 2-3 56 57 58 59 60 61 62 63 64 65 66 2-4 67 68 69 70 71 In this example, the length of real axis is equal to the length of conjugate axis, like this kind of hyperbola it is called hyperboliod right- angle, because the fore points are formed square shape.
