Vectors are often used in navigation. In many cases, they are easier to relay than instructions based on grid systems. Sports teams and sport commentary rely on vectors as well.Know More
Vectors sound complicated, but they are common when giving directions. For example, telling someone to walk to the end of a street before turning left and walking five more blocks is an example of using vectors to give directions. Telling someone to walk to where 25th Street intersects with 8th Avenue, on the other hand, is not a use of vectors.
Navigating by air and by boat is generally done using vectors. Planes are given a vector to travel, and they use their speed to determine how far they need to go before turning or landing. Flight plans are made using a series of vectors.
Sports instructions are based on using vectors. Wide receivers playing American football, for example, might run a route where they run seven yards down the field before turning left 45 degrees and running in that direction. Sports commentary also depends on vectors. Only a few sports have fields with grids, so discussions revolve around the direction and speed of the player. Illustrations of plays in a variety of sports rely on simple vector images.Learn more about Numbers
People find decimals in many places during daily life: on price tags of items at clothes stores, on bank credit card statements and even on food nutrition labels. Decimals exist in many places and play an important role in daily life. Small changes in decimal placements lead to big changes in price, quantity, expenditures and savings.Full Answer >
The number pi, represented by the symbol π, is used in everyday life to calculate the radius or circumference of circles and in design and construction. Pi is an irrational number, often approximated to 3.14, that was discovered by Greek mathematicians as a ratio to relate the diameter of a circle to the circumference.Full Answer >
Prime numbers are used to encrypt information through communication networks utilized by cell phones and the Internet, according to PBS. One common encryption code uses the RSA algorithm to secure credit card transactions transmitted from one source to the next. Slate reports that encryption keys are based on very large prime numbers.Full Answer >
Integers are used in daily life when performing tasks such as recording temperature changes, taking inventory of supplies, and depositing or withdrawing money from a bank. For example, in terms of temperature changes, a rise in temperature of 30 degrees Fahrenheit is represented by the integer +30. A drop in temperature of the same magnitude would be recorded as -30.Full Answer >
