Geometry and Trigonometry
Although many people find geometry and trigonometry intimidating, the small investment required to understand a few basic principles in these disciplines can pay large dividends. For example, what if you needed to find the distance between two points, or rotate one object around another? These small tasks are needed more often than you may think, and are easier to accomplish than you may realize.
Movement Along an Angle
Earlier we discussed velocity as a vector quantity because it combined magnitude and direction.
Algebraic concepts on the GMAT are those normally covered in a first-year high school algebra course. The Quantitative Section does NOT cover the following skills and math areas: • • • • • • Complex calculations involving large and/or unwieldy numbers Advanced algebra concepts Formal geometry proofs Trigonometry Calculus Statistics (except for simple probability, arithmetic mean, and median)
Geometry and Trigonometry
storing the current angle in a variable (line 12) and incrementing the angle to the next button position (line 13). The value of the angle is converted from degrees to radians using deg2rad(), the utility function we’ve discussed before, at the end of the script. The button is then created using the library symbol with the SatelliteButton linkage class, centered, and positioned on the circle defined by the mainButton center point and radius. The same technique to move an object along a circular path is used here.
So you wanna be a hotshot game designer? Well, if you have a basic grasp of Macromedia Flash MX, you can.
Unafraid to tackle some of the more complicated aspects of game creation (including physics and
trigonometry!), this comprehensive reference covers it all. Macromedia Flash Game Design Demystified starts
out with the basics: planning, adapting ActionScript techniques, using introductory Flash game techniques,
and more. Then it gets down to the real business of building simple games.
What can your book do? End up supporting literacy worldwide! End up in the land fill. Everyone in on campus has an old book or two laying arround . Run the book drive with Better World Book to collect them and you could: Support literacy initiatives in Africa, Southeast Asia, Latin American or the U.S Raise funds for your campus group.
I wrote this text for a one semester course at the sophomore-junior level. Our experience with students
taking our junior physics courses is that even if they’ve had the mathematical prerequisites, they usually need
more experience using the mathematics to handle it eﬃciently and to possess usable intuition about the processes
involved. If you’ve seen inﬁnite series in a calculus course, you may have no idea that they’re good for anything.
The set of arithmetic operations that a particular ALU supports may be limited to addition and subtraction, or might include multiplication, division, trigonometry functions such as sine, cosine, etc., and square roots. Some can only operate on whole numbers (integers) whilst others use floating point to represent real numbers, albeit with limited precision. However, any computer that is capable of performing just the simplest operations can be programmed to break down the more complex operations into simple steps that it can perform.
Place bottle tops, top-side up, to make a shape. Record the co-
ordinates of the corners of the shape. Place another set of bottle
tops, teeth-side up, to show the image of the shape when it has been
enlarged by a scale factor of 2 from the origin. Record these new
co-ordinates. Compare the two sets of co-ordinate pairs.
Show different shapes enlarged by a scale factor of 2 from the
origin. Note the co-ordinates and investigate how the sets of co-
ordinates are related.
Now try enlargements of other scale factors such as 5, 1/2, -2.
