It is important for any beginning woodturner to learn about and master the process of basic trig, but many turners are in such a hurry to learn this that they begin with the wrong tool. You can spend hundreds of dollars on online trig worksheets to improve your accuracy, but it is much more valuable to focus on using something you already know and have a foundation for. The last thing you want to do is to start using a workbook that does not teach you trig, because it will only slow you down. Fortunately, if you use an Angle of Elevation and Depression Trig Worksheet, you can use trig without ever needing to purchase a new one.
One of the first things that most beginners do when learning trig is to spend a lot of time doing trig worksheets that are old and outdated. The fact is that these old trig worksheets do not teach you the nuances of trig, but rather, they teach you how to do the trig without understanding it. Once you understand trig, you will be able to go from looking at a computer screen to doing it on a real turner. At this point, you will also have a base for your trip and a base to build from.
Angles and Inverses. Take time to understand the meaning of the Angle of Elevation and the Depression. These are the two sides of the trig, and they go one way, then the other way. Sometimes, they are symmetrical, but often they are not. Take some time to learn to do both of these angles correctly.
What does the Angle of Elevation represent? It represents the amount of a turn, such as 60 degrees. The Angle of Depression is how far a turn is to the right, such as a 90-degree turn, and it is also the amount of a turn, represented by the difference between the two lines. Here is where things get tricky, because if you consider the lower left hand side of the Angle of Elevation as being zero, then the lower right hand side of the Angle of Depression is a positive value. Knowing this makes a big difference to your turn, but you can use this to your advantage by using the Angle of Elevation and the depression in conjunction with the angles of the other sides. For example, if you want to turn your wood like a clock, then you should turn it at a constant rate, thus creating a clock-like Angle of Elevation and depression.
What do the Angle of Elevation and the depression represent? The angle of elevation is the angle between the upper side of the angle of depression and the upper side of the angle of elevation, and this is called the angular of elevation.
To do a right turn, use the angle of elevation and the depression. For a left turn, use the angle of depression and the elevation. Remember to always center the turn around the target, and use only one side of the trig. For more complex turns, use the math to perform the turn without using the trig.
A good angle is always easy to do, and this Angle of Elevation and Depression worksheet will help you master how to do just that. Why not take a look today?
