We can use our predefined right triangle relationships to figure out the side lengths of the triangle's remaining two sides. This branch of math, known as trigonometry, has everyday practical applications such as construction, GPS, plumbing, video games, engineering, carpenter work and air flight...
Explain how to use the Pythagorean theorem and how it relates to the terms sine, cosine, and tangent. Six Trigonometric Ratios: Given a right-triangle△ABChaving the following properties: ∠Cis a right angle; m∠A≤m∠Blabeled in the usual manner. ...
Back to top 11. How to average blank as zero The AVERAGE function ignores blank cells , however, there is a simple workaround that allows you to count 0's (zeros) to the total number of observations. Keep in mind, the average is calculated like this: Sum / total number of items. A...

Full recalculation: Pressing F9 outside of Edit mode will recalculate all formulas in the workbook. Remember to be careful not to accidentally overwrite parts of your formula when using F9. Always exit with Esc rather than Enter to preserve the original formula. However, if you make a mistake...
we can then calculate the position of the stars. This is true for any star or object as long as its declination and right ascension are known. Simple spherical trigonometry of 3 known variables, one equation for altitude and one equation for azimuth for every star. That’s all there is t...
In addition to degrees, CAD software often offers the option to measure angles in radians or gradients. Radians are another way of measuring angles, commonly used in trigonometry. Gradients, on the other hand, are a measurement system based on a 400-degree circle. While degrees are the most ...
Direction of a Single Force Vector The direction of the force isn't the focus of this question, but it's easy to work out based on the triangle of components and the resultant force from the last section. You can work out the direction using trigonometry. The identity best-suited to the...
In trigonometry, if the sides of a triangle are all different lengths (i.e. unequal sides), we can determine it to be scalene. This also means that the interior angles will all be distinct. TL;DR (Too Long; Didn't Read) The area of a scalene triangle with base b and height h is...
Since triangles always follow concrete rules we can use concepts like the Pythagorean theorem formula — and later, trigonometry — to find all the parameters of a triangle (angle values, lengths) if at least one of them is known. The Pythagorean theorem is the simplest of these concepts and...
