See Article History Trigonometry, the branch of mathematics concerned with specific functions of angles and their application to calculations. There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine sin , cosine cos , tangent tan , cotangent cot , secant sec , and cosecant csc. These six trigonometric functions in relation to a right triangle are displayed in the figure. For example, the triangle contains an angle A, and the ratio of the side opposite to A and the side opposite to the right angle the hypotenuse is called the sine of A, or sin A; the other trigonometry functions are defined similarly. These functions are properties of the angle A independent of the size of the triangle, and calculated values were tabulated for many angles before computers made trigonometry tables obsolete.

The marketing mix refers to the set of actions, or tactics, that a company uses to promote its brand or product in the market. However, nowadays, the marketing mix increasingly includes several other Ps like Packaging, Positioning, People and even Politics as vital mix elements. What are the 4Ps of marketing?

The second is the SI base unit of time, commonly understood and historically defined as 1 ⁄ of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each. Another intuitive understanding is that it is about the time between beats of a human heart. Mechanical and electric clocks and watches usually have a face with.

Controversy[ edit ] Anthropologist Helen Fisher in What happens in the dating world can reflect larger currents within popular culture. For example, when the book The Rules appeared, it touched off media controversy about how men and women should relate to each other, with different positions taken by New York Times columnist Maureen Dowd  and British writer Kira Cochrane of The Guardian. Sara McCorquodale suggests that women meeting strangers on dates meet initially in busy public places, share details of upcoming dates with friends or family so they know where they’ll be and who they’ll be with, avoid revealing one’s surname or address, and conducting searches on them on the Internet prior to the date.
Don’t leave drinks unattended; have an exit plan if things go badly; and ask a friend to call you on your cell phone an hour into the date to ask how it’s going. If you explain beautifully, a woman does not look to see whether you are handsome or not — but listens more, so you can win her heart. That is why I advise our boys to read stories and watch movies more and to learn more beautiful phrases to tell girls.
The Internet is shaping the way new generations date. Facebook , Skype , Whatsapp , and other applications have made remote connections possible. Online dating tools are an alternate way to meet potential dates. The average duration of courtship before proceeding to engagement or marriage varies considerably throughout the world.

Building a Healthy Relationship from the Start The Beginning Stages While the early months of a relationship can feel effortless and exciting, successful long-term relationships involve ongoing effort and compromise by both partners. Building healthy patterns early in your relationship can establish a solid foundation for the long run.
When you are just starting a relationship, it is important to: Build a foundation of appreciation and respect. Focus on all the considerate things your partner says and does. Happy couples make a point of noticing even small opportunities to say “thank you” to their partner, rather than focusing on mistakes their partner has made. Explore each other’s interests so that you have a long list of things to enjoy together.
Try new things together to expand mutual interests. Establish a pattern of apologizing if you make a mistake or hurt your partner’s feelings. Saying “I’m sorry” may be hard in the moment, but it goes a long way towards healing a rift in a relationship. Your partner will trust you more if he or she knows that you will take responsibility for your words and actions.

In base, each digit in a position of a number can have an integer value ranging from 0 to 9 (10 possibilities). The places or positions of the numbers are based on powers of Each number is 10 times the value to the right of it, hence the term base
That means that every second, minute and every other division of time counted by the clock will be the same duration as any other identical division of time. But a sundial which measures the relative position of the sun in the sky called apparent time, does not keep uniform time. The time kept by a sundial varies by time of year, meaning that seconds, minutes and every other division of time is a different duration at different times of the year.
The time of day measured with mean time versus apparent time may differ by as much as 15 minutes, but a single day will differ from the next by only a small amount; 15 minutes is a cumulative difference over a part of the year. The effect is due chiefly to the obliqueness of earth’s axis with respect to its orbit around the sun. The difference between apparent solar time and mean time was recognized by astronomers since antiquity, but prior to the invention of accurate mechanical clocks in the mid th century, sundials were the only reliable timepieces, and apparent solar time was the generally accepted standard.
Events and units of time in seconds[ edit ] Fractions of a second are usually denoted in decimal notation, i. Multiples of seconds are usually expressed as minutes and seconds, or hours, minutes and seconds of clock time, separated by colons, such as It rarely makes sense to express longer periods of time like hours or days in seconds, because they are awkwardly large numbers. Some common units of time in seconds are: Some common events in seconds are: The metric system unit becquerel, a measure of radioactive decay, is measured in inverse seconds.

Let’s start with general definitions. Mathematics is made of 50 percent formulas, 50 percent proofs, and 50 percent imagination. American coffee is good for lemmas. An engineer thinks that his equations are an approximation to reality. A physicist thinks reality is an approximation to his equations. A mathematician doesn’t care. Old mathematicians never die; they just lose some of their functions. Mathematicians are like Frenchmen: Poincare What is a rigorous definition of rigor?
