PROPERTIES OF SINE AND COSINE FUNCTIONS: 1. The sine and cosine functions are both periodic with period 2π. 2. The sine function is odd function since it’s graph is symmetric with respect to the origin‚ while the cosine function is an even function since it’s graph is symmetric with respect to y axis. 3. The sine functions: a. Increasing in the intervals[0‚ π/2]and [3π/2‚ 2π]; and b. Decreasing in the interval [π/2‚ 3π/2]‚over a period of 2 π. 4. The cosine function is: a. Increasing in the interval

AP Lab #5 Plant Pigments/Photosynthesis I. Identifying the Effects of Different Variables of Light and Carbon Dioxide on the Rate of Photosynthesis and Observing the Separation of Pigments Through Chromatography II. Introduction Plants have a variety of pigments‚ all of which absorb a different color of light. The three main pigments are chlorophyll a‚ chlorophyll b and carotenoids. Chlorophyll a is the primary plant pigment that absorbs red and blue light‚ which ultimately appears green to the human eye

Egg Lab Write Up The purpose of this lab was to depicked the many properties of diffusion such as isotonic‚ hypotnonic‚ and hypertonic‚ so that students could have a clear visual example to go by for future refrences. We also did this to learn about selective permeability and osmosis. Our original hypothesis stated that the vinegar would react with the calcium in the shell to create CO2 bubbles. Note I said the original hypothesis as this experiment took coarse over a four day period‚ in which

Does everyone learn language same way? What are the rules of language? “What is Language?” by Neil Smith and Deirdre Wilson answers these questions and more by highlighting the three major theories of modern linguistics. The first modern linguistic theory claims that language is govern

Title: Freezing and Melting of Paradichlorobenzene Purpose: Melting‚ freezing‚ and boiling points are properties that can easily be determined and help in identifying a substance. These properties can be found in chemical literature ad reference tables‚ and can be used to distinguish a pure substance from many other pure substances. In this lab you will use the pure substance Paradichlorobenzene and determine its melting an freezing points by warming and cooling a sample of the substance

Silveira Date of Submission: September 25‚ 2013 Lab Section: CHE110L*Z Purpose The purpose of this experiment is to use two common laboratory methods to see how mixtures can be separated based on physical properties. Paper chromatography will be used to separate the dye colors from M&M candy to see which colors contain yellow #5. Gravimetric separation will be used to separate salt and sand from a mixture. Procedure The procedure for this lab can be found on pages 16 – 30 in “General Chemistry

claimed that by growing and using transport biofuels in the UK‚ carbon dioxide emissions could be cut by 50 – 60% compared to those from fossil fuels‚ as well as reducing the need for foreign imports‚ and so could lead to a reduction in greenhouse gases. This is backed up by an article which states that farmers in the UK see biofuels as a way of providing the nations motorists with a low carbon fuel supply (Kendall‚ 2006). Kendall makes clear that the demand for both fuel and food crops could be met

Gas Laws Lab Introduction: The four basic physical properties of a gas sample are pressure‚ volume‚ temperature‚ and number of moles. The volume simply indicates the volume of the container since a gas will take up all space available to it. The temperature indicates the average kinetic energy of the gas particles. For gases‚ the temperature must be converted to the Kelvin unit. The pressure of the gas indicates the number of collisions with each other and the wall of the container. The number
