What is SEC on a calculator?
There are no specific keys or menu items on the graphing calculator for the secant, cosecant and cotangent functions. Consequently, you will have to use your knowledge of these functions when working with them on the graphing calculator.
What is SEC A and SEC B?
The socioeconomic classification (SEC) groups urban Indian households on the basis of education and occupation of the chief wage earner (CWE: the person who contributes the most to the household expenses) of the household into five segments (SEC A, SEC B, SEC C, SEC D and SEC E households in that order).
What is SEC in market research?
The socio-economic classification (SEC) is a measure used to classify and target consumers based on certain parameters, as defined by Market Research Society of India (MRSI) in 2011. It is based on two variables: Education of chief earner.
What is new consumer classification system?
New Consumer Classification System (NCCS) is the new tool for classifying consumers in India. … It was almost three decades ago that socio-economic classification (SEC) was introduced in the country to classify consumers into different groups. Over time, flaws were noticed in the system.
What is the formula of Sec A?
Secant (sec) – Trigonometry function In a right triangle, the secant of an angle is the length of the hypotenuse divided by the length of the adjacent side. In a formula, it is abbreviated to just ‘sec’. … They can be easily replaced with derivations of the more common three: sin, cos and tan.
What is sec theta?
The reciprocal cosine function is secant: sec(theta)=1/cos(theta). The reciprocal sine function is cosecant, csc(theta)=1/sin(theta). … And the 3 new functions are secant theta, cosecant theta and cotangent theta.
What is SEC system?
The Sec system utilises two different pathways for secretion: the SecA and signal recognition particle (SRP) pathways. … SRP is a ribonucleoprotein (protein-RNA complex) that recognizes and targets specific proteins to the endoplasmic reticulum in eukaryotes and to the cell membrane in prokaryotes.
What is trigonometry formula?
Basic Formulas By using a right-angled triangle as a reference, the trigonometric functions or identities are derived: sin θ = Opposite Side/Hypotenuse. cos θ = Adjacent Side/Hypotenuse. tan θ = Opposite Side/Adjacent Side. sec θ = Hypotenuse/Adjacent Side.
