How do I remember the trigonometric table?
Question :- How do I remember the trigonometric table?Answer :-This technique was taught by my teacher.It was really useful for me since I don’t remember these values.For teaching you, it took me 1 page. But 4–5 lines in rough column is enough.For cosecθ, secθ and cotθ :-Thank you!Jai Shri Ram_/\_
Can you tell me a little bit 'bout educational system in America?What I need to do to become a good student?
Not all US high schools are as bad as that other poster made them out to be. I should know, I went to one. The problem most of the bad schools have isthat they are filled with stupid poor people. Avoid inner city schools. In general what you want to do to be a good student is just make the teachers think you are trying hard. If you do that they will grade you easier and give you the benfit of the doubt in most circumstances. Yes, you shoucl participate in extracurricular activities. They look good on applications and they keep you busy so you dont fall in with a crowd of drug addict losers.
What kind of math do computer programmers use?
Basic Programming MathBinary math is at the core of how any computer operates. Binary is used to represent each number in the computer. Reading and simple mathematical operations with binary is critical for low-level programming of hardware. Understanding how to work with hexadecimal number system is required for many programming functions such as setting the color of an object. Standard arithmetic is used in many functions of programming. Addition, subtraction, multiplication and division is used in almost every program written. Algebra is used to solve simple problems that many computer programmers will encounter.How Is Math Used in Computer Engineering?Advanced Programming MathObtaining a computer science degree requires completing many math classes. These include college algebra, statistics, calculus I and calculus II. These classes are applied in two different ways for computer programming. The most obvious is using the math taught to solve complex equations. The less obvious is the skills learned to master advanced math is similar to the skills required to build complex applications. These skills include logic and following complicated step-by-step processes.Application-Specific MathThe application for the program being created will often dictate the specific type of math techniques required. Linear algebra is often used for transformation of matrices. Matrix transformation is found in both 2D and 3D modeling as seen in computer-aided design and photo editing software. Differential equations can be found in software to simulate traffic or health conditions. Statistics is used in many computer programming applications including polling systems, reports and card games.
What is staging table?
Staging table is a temporary table that is used to stage the data for temporary purpose just before loading it to the Target table from the Source Table. As the data resides temporarily, you can do various stuff on that data like:De-dupingCleansingNormalizing to multiple tablesDe-Normalizing from multiple to a single table.Extrapolatingetc.Staging or Factory term is typically used in ETL or Extract Transform Load processes, where you load data from one or more Source tables to a Target table.Image Source: What is ODS (Operational Data Store)As you can see in above image, the Data is being pulled from multiple Source DBs and moved to Staging/Factory Database before loading to the Data Warehouse.In this scenario:First load pulls all data from the Source table.Second and successive loads pulls only delta or incremental data which consists of new rows or modified rows at the Source.~ SQL with Manoj
Aircraft seating - statistics help?
I am stuck on the following problem and not sure whereto begin. I know that it isn't a Normal Distribution because the mean doesn't equal 0 and standard deviation doesn't equal 1. CTE 7: Designing Aircraft Seating The sitting distance is defined as the distance from theseat back cushion to the seat in front. It accommodates thebuttock-to-knee length plus any additional space to providecomfort. Determining this distance is very important. If thedistance is too large, space is wasted and rows of seats may beeliminated. It is estimated that eliminating a single row of seatsin an aircraft can cost around 8 million dollars over itslife. If the distance is too small, passengers will beuncomfortable and may choose a different airline. Use the data in the table to determine the requiredseating distance. The following choices must be carefullymade. 1) Should the entire population be accommodated? If not,what percentage of the population are you willing to exclude?Explain your reasoning. 2) How much extra room are you providing for thepassengers comfort? Explain. 3) Use the given information to determine the sittingdistance. Identify the choices and decisions that were made in thatdetermination. The following data is a summary from measurements oflarge numbers of people. Buttock-to-Knee Length Mean Standard Deviation Distribution Males 23.5 in. 1.1 in. Normal Females 22.7 in. 1.0 in. Normal
