1. Explain the terms area of convergence and area of origin and explain what each term reveals to an investigator. The area of convergence of an impact spatter pattern is the area the individual stains emanated from on a two-dimensional plane. The area of origin of a bloodstain pattern in three-dimensional space may represent the position of the victim or suspect when the stain-producing event took place. These areas can determine and reveal to an investigator the direction of force‚ angle of impact

Previous exam questions on area between functions and volumes of solids. 1. Let f(x) = cos(x2) and g(x) = ex‚ for –1.5 ≤ x ≤ 0.5. Find the area of the region enclosed by the graphs of f and g. (Total 6 marks) 2. Let f(x) = Aekx + 3. Part of the graph of f is shown below. The y-intercept is at (0‚ 13). (a) Show that A =10. (2) (b) Given that f(15) = 3.49 (correct to 3 significant figures)‚ find the value of k. (3) (c) (i) Using your value of k‚ find f′(x). (ii) Hence

Surface Area Formulas In general‚ the surface area is the sum of all the areas of all the shapes that cover the surface of the object. Cube | Rectangular Prism | Prism | Sphere | Cylinder | Units Note: "ab" means "a" multiplied by "b". "a2" means "a squared"‚ which is the same as "a" times "a". Be careful!! Units count. Use the same units for all measurements. Examples |Surface Area of a Cube = 6 a 2

[pic] An ellipse is a curve that is the locus of all points in the plane the sum of whose distances [pic] and [pic] from two fixed points [pic] and [pic] (the foci) separated by a distance of [pic] is a given positive constant [pic] [pic] While [pic] is called the major axis‚ [pic] is the semi major axis‚ which is exactly

First of all I think it is important to define what we consider to be an important learning environment before we establish what learning centers are placed within our classroom‚ and the age range that will be attending. The learning environment should always meet the children’s developmental needs. It should make all children including ones with special needs -feel secure‚ comfortable and a place where they belong. The interest areas should allow the children choices to explore‚ make things‚ experiment

75). Life-course Theories Cognitive Development (Jean Piaget) ... children gradually develop cognitive abilities through interaction with their social setting through the process of socialization. Piaget contends that children are not merely passive recipients of social stimuli; they are actively engaged in interpreting their environment as they attempt to adjust to it. Cognitive ability‚ in Piaget’s theory‚ advances in stages. * Stages of Cognitive Development 1. Sensorimotor

Personal social and emotional has three aspects‚ making relationships‚ managing feelings and behaviour and self-confidence and self-awareness. This area is all about the child’s relationships with other people and themselves.

Surface area Surface area is the measure of how much exposed area a solid object has‚ expressed in square units. Mathematical description of the surface area is considerably more involved than the definition of arc length of a curve. For polyhedra (objects with flat polygonal faces) the surface area is the sum of the areas of its faces. Smooth surfaces‚ such as a sphere‚ are assigned surface area using their representation as parametric surfaces. This definition of the surface area is based on methods
