Suppose, If both X and Y are moving in the same direction at the same time at a speed of x meter per second and y meter per second respectively, then. The time required for X to meet Y can be calculated as. Distance refers to the length of the path covered by an object or person. You can calculate the distance travelled by an object if you know how long and how fast it moved. The distance travelled by an object or person in terms of speed and time can be calculated as :.
Time refers to the duration in hours, minutes, or seconds spent to cover a particular distance. Time taken by a moving object to a cover a certain distance at a given speed is calculated as :. The speed, time, and distance of a moving object can be calculated by using the following formulas of distance speed and time. Distance Speed Time Formula is given as:. The theorem is often credited to the greek mathematician Pythagoras c.
The pythagorean theorem where also known by Babylonian and Chinese mathematicians before Pythagoras. It is not known whether the theorem were discovered once or many times in different places.
Pythagorean triples were discovered by the babylonians, from to BC, even though they never mentioned any triangles. For example, a stereopticon, or stereoscope, which was a popular device in the 19th century , uses parallax to display photographs in 3D. Two pictures mounted next to each other are viewed through a set of lenses.
Each picture is taken from a slightly different viewpoint that corresponds closely to the spacing of the eyes. The left picture represents what the left eye would see, and the right picture shows what the right eye would see. Through a special viewer, the pair of 2D pictures merge into a single 3D photograph. The modern View-Master toy uses the same principle.
Another method for capturing and viewing 3D images, Anaglyph 3D , separates images by photographing them through colored filters. The images are then viewed using special colored glasses. One lens is usually red and the other cyan blue-green. This effect works for movies and printed images, but most or all of the color information from the original scene is lost.
Some movies achieve a 3D effect using polarized light. The two images are polarized in orthogonal directions, or at right angles to each other, typically in an X pattern, and projected together on the screen.
The special 3D glasses worn by audience members block one of the two overlaid images to each eye. At Cuemath , our team of math experts is dedicated to making learning fun for our favorite readers, the students!
Through an interactive and engaging learning-teaching-learning approach, the teachers explore all angles of a topic. If a person stands and looks down at an object, the angle of depression is the angle between the horizontal line of sight and the object. An angle of elevation of one location relative to another is always congruent equal in measure to the angle of depression of the first location relative to the second.
The angle of elevation of an object as seen by an observer is the angle between the horizontal and the line from the object to the observer's eye the line of sight. Using trigonometry, if we are provided with any of the two quantities that may be a side or an angle, we can calculate all the rest of the quantities.
