When a number is expressed in the form of x multiplied by 10^y such that, x < 10 and y is an integer, the number is said to be in standard form. Standard form of expressing numbers finds its use in scientific and statistical fields. This video demostrates how to express, as well as perform basic mathematical operations namely, addition/subtraction, multiplication and division of numbers in the standard form using four examples/mathematical problems. The first two examples demostrate multiplic...
Probability computation is a complex process and even using a calculator can be difficult. But normal probability calculations can be performed quickly with the help of calculator once you know how to use it. So when you have to calculate a probability from a normal distribution you can use the functions on your scientific calculator. You can use the normal CDF function from you calculator to compute the area under a normal curve. The function requires lower band and upper band values, the me...

First remove the cover of your calculator and measure its length and width using the ruler. 2. Now cut a piece of paper with the exact measurements taken from the cover. 3. Write all you need on the paper and fix it in the cover carefully. 4. Make sure the paper does not fall out and then put the cover to the back of your calculator. 5. Finally test ...
If you have a fossil, you can tell how old it is by the carbon 14 dating method. This is a formula which helps you to date a fossil by its carbon. If a fossil contains 60% of its original carbon, how old is the fossil? The half life of carbon 14 is 5600 years. That means this is how long it takes for half the nuclei to decay. After 5600 years, if we start with a gram, we end up with half a gram. This rather complex formula shows you how to solve this puzzle using accepted scientific methods.
In this video from Socoolscienceshow, Crazy Chris explains to us how magicians make things disappear. For this he uses a plate, cup, and a napkin. You cover the cup and plate with a napkin. He removes the napkin with the cup and shows that he taped the cup to the bottom of the plate so they are both removed at the same time. To maintain the look of the cup in that napkin when it's removed he shows that he trace the cup onto some construction paper cut it out, and tape it to the napkin. Then h...
In this video tutorial the author shows how to use the Cosine Law. He shows how to find an angle of a triangle where he know all the sides of a triangle, using the cosine Law. He uses a lower case letter to designate a side and a capital letter to designate an angel apposite to that side. He gives the formula for the cosine law using a triangle as an example. Now he goes on and demonstrates how to use a scientific calculate. He shows how to use the degree mode in the calculator to solve these...

Before there was Gray's Anatomy, physicians and medical students used anatomical flap books to explore the inner workings of the human body—a scientific illustrated guide that takes its name from the moveable paper flaps that can be "dissected" to reveal hidden anatomy underneath. Similar to pop-up books, these instructional tools mimic the act of human dissection, allowing doctors and students to study the intricacies of the body normally concealed by flesh.
