MEDICAL APPLICATIONS OF VOLUME | REAL LIFE MATH

  As you probably know “An object’s volume describes the amount of space it contains”. But, have you ever thought what could be the practical applications of volume? In medicine, volume measurements are used to characterize brain damage, lung function, sexual maturity, anemia, body fat percentage, and many other aspects of health. A few of these uses of volume are described below. 1.)  Brain Damage from Alcohol Using modern medical imaging technologies such as magnetic resonance imaging (MRI), doctors can take three-dimensional digital pictures of organs inside the body, including the brain. Computers can then measure the volumes of different parts of the brain from these digital pictures, using geometry and calculus to calculate volumes from raw image data. MRI volume studies show that many parts of the brain shrink over time in people who are addicted to alcohol. The frontal lobes—the wrinkled part of the brain surface that is just behind the forehead—are strongly affected...

BIOLOGICAL APPLICATIONS OF PRIME NUMBERS | REAL LIFE MATHEMATICS

  As you probably know “ A number having exactly two factors (one is the unity and another is the number itself), is called A Prime Number. But, have you ever thought what could be the Real Life Applications of Prime Numbers? Here is the Biological Application of Prime Numbers. Plant-eating insects called cicadas spend a lot of their life underground in one form, before emerging as adults. In some types (species) of cicada, this appearance occurs at the same time for all the adults in the region, every 13 or 17 years. 13 and 17 are prime numbers. Coincidence?  Scientists who have studied the species of cicadas do not think so. Rather, they think, the use of a prime number for the life cycle has been a response to the pressure put on cicada population by other creatures who utilize them as food . In other words, the cicadas are the prey and the creatures lying in wait when they emerge to the surface are the predators. Researchers have used mathematical ways to model the so-cal...

REAL LIFE APPLICATIONS OF TRIGONOMETRY | REAL LIFE MATH.

  Triangle trigonometry has many applications that help find unknown lengths or angle measurements. For instance, paintings, motion pictures, and televisions have ideal viewing distances in order to create the greatest possible image from the eye. The triangle is formed between the view and the top and bot- tom (or the sides) of the viewing object. Here are the 5 best Real Life Applications of Trigonometry. 1.)  In Astronomy Astronomers use triangle trigonometry to determine distances and sizes of objects. For example, the distance from the earth to the moon, and earth to the sun, can be found by identifying their angles from the horizon during an eclipse. The height of a solar flare can also be determined by measuring the angle from the sun to the tip of the flare, and using distance information about the earth and sun. 2.)  In Engineering Work Trigonometry can be used to find unknown lengths or angle measurements. In a situation involving right triangles, only a side le...

REAL LIFE APPLICATIONS OF AREA | REAL LIFE MATH

As you probably know- "Every real-world object and every geometrical figure that is not a point or a line has a surface. The amount or size of that surface is called the object’s or figure’s area." but, have you ever thought what could be the real life applications of area? In this post you are going to know about the Real Life Applications of Area. 1.) DRUG DOSING The amount of a drug that a person should take depends, in general, on their physical size. This is because the effect of a drug in the body is determined by how concentrated the drug is in the blood, not by the total amount of drug in the body. Children and small adults are therefore given smaller doses of drugs than are large adults. The size of a patient is most often determined by how much the patient weighs. However, in giving drugs for human immunodeficiency virus (HIV, the virus that causes AIDS), hepatitis B, cancer, and some other diseases, doctors do not use the patient’s weight but instead use the patien...

SHORT TRICK TO MULTIPLY ANY TWO DIGITS NUMBERS.

You should observe to learn the working of this method. Step - 1: Multiply the unit digits (rightmost digits) of both the numbers, Step - 2: Add the cross product of the digits as shown below: Step - 3: Multiply the ten’s digits (leftmost digits) of both the numbers. Note: If the results obtained in step 1 and step 2 have more than one digit, note down the unit place of the result and carry over the ten’s place of the result to the left. Let us understand the process through some examples: Example 1: Solve 13 × 12 Step - 1: Multiply the unit digits (rightmost digits) of both the numbers, Step - 2: Add the cross product of the digits as shown below: Step - 3: Multiply the ten’s digits (leftmost digits) of both the numbers. So,13 × 12 = 156 Now before you get too excited, I have shown you only half of what you need to know. Suppose the problem is Example 2: Solve 28 × 35. Step- 1: Multiply the unit digits (rightmost digits) of both the numbers, Step - 2: Add the cross product of the digi...

SHORT REVISION ON ALGEBRAIC IDENTITIES.

  As you probably know “An Algebraic identity is an algebraic equation that is true for all values of the variables occurring in it.” These Identities play a vital role in any algebraic or mathematical calculation. So, this post is made for the short revision of the Algebraic Identities. Some of these are : ·         ( x + y ) 2 = x 2 + 2 xy + y 2 ·         ( x - y ) 2 = x 2 - 2 xy + y 2 ·         x 2 – y 2 = ( x + y ) ( x – y ) ·         ( x + a ) ( x + b ) = x 2 + ( a + b ) x + ab ·         ( x + y + z ) 2 = x 2  +  y 2  +  z 2 + 2( xy  +  yz  +  zx) ·         ( x + y ) 3 = x 3 + y 3 + 3 xy ( x + y )  ·         ( x – y ) 3 = x 3 – y 3 – 3 xy ( x – y ) ·  ...
