How to Draw a Flower on a Graphing Calculator (Equations)

Here's how u draw a flower on a graphing calculator. On this Video i am using an iPhone App named Graphic Function Which is really helpful on a Regular, Algebraic, Statistic, Trigonometric and Calculus Basis. You can also use a Regular Graphing Calculator such TI-83, TI-83 Plus Etc. The only diference is that interface.. I've have searched google for some equations that will help me graph flower but then all i see are bunch of comments saying Just draw it-__- So i end up with my own equation that i based from my Trigonometry notes from last semester. A simple basis of formula i recover is "tan(4theta)". took me a couple of brainstorms with numbers then hoorayy, i got it.. When u punch in sin(13theta) on r1; then sin(10theta) on r2; then cos(10theta) or r3 and press graph, u'll get a sharp edged flower. however, punching in the number with a slight difference will smoothen its edges. try punching in cos(30) on r1; sin(4theta) on r2; cos(4theta) or r3 then press graph then zoom 2 then press enter Please Set ur Calculator to RADIAN instead of DEGREE and POLAR instead of FUNCTION. To do so press MODE then u'll see. Confirm by pressing ENTER. Have Fun Everyone. Hope u Enjoyed it.

Can Casio Catch Texas Instruments?

!±8± Can Casio Catch Texas Instruments?

Stop into almost any secondary school mathematics classroom in America today, and you will find that Texas Instruments graphing calculators dominate the scene. Back in the early 90's, Texas Instruments began a pattern of releasing a series of graphing calculators that were all extremely similar, with only small updates to the hardware and operating system: the TI-81, TI-82, TI-83, and lastly, the TI-84, in 2004. They were all received with great popularity, and since each successor was so similar to the one that came before it, it was simple for adults and kids to catch on.

After a decade of Texas Instruments dominating the calculator market, you may wonder if there's even another choice out there any more. The short answer is, "yes," and it comes through Casio of America. Casio has been promoting itself in two ways in recent years, simplicity and affordability. Their products live up to the press on both fronts.

In terms of cost, Casio products are significantly less than the TI products they compete with. Of course, it's not an apples to apples comparison, but the Casio 9860GII and 9750GII are both significantly cheaper than any TI graphing calculators. The 9750GII actually retails for under , making it by far the lease expensive graphing calculator from a top manufacturer on the market. The graphical menu system on these devices is also extremely easy for novices to use.

The future of Texas Instruments, however, is the TI-Nspire. Introduced in 2007, this device features high resolution, grey scale display, drop down menus, point and click interface, and the ability to create documents. Casio has had nothing to compete against this calculator until now. In October, Casio announced their new calculator, the Casio Prizm. It's a high resolution, color calculator with the ability to graph functions right onto photographs. The marketing video doesn't hide the fact that Casio is targeting the TI-Nspire with this release.

The battle for marketplace supremacy is once again on. Texas Instruments has a commanding head start, but Casio now has an innovative new product. When the Casio Prizm comes out in early 2011, expect a huge struggle for market share between these two companies.

Myspace Countdown Clocks

!±8± Myspace Countdown Clocks

MySpace is one of the most popular social networks on the internet with over 100 million users and a rank of 6th place on Alexa.com. Because of the ability to greatly customize profile pages many sites have been created to help MySpace users create custom pages with graphics, name generators, photo album scrollers and many more widgets.
I am going to concentrate on one particular widget in this article and that is the countdown clock widget.

Countdown clocks

A countdown clock widget allows you to countdown to a certain day, for example Christmas day is on the 25th of December, so you would enter that date in the countdown widget and the widget will then display a count down in days, hours, minutes and seconds till the 25th of December. There are a number of different types of countdown widget available including birthday, wedding, vacation, public holidays and many more. The most popular countdown timer widget at the time of writing this article is the Pregnancy countdown timer with over 3000 searches a day. Pregnancy countdown timers are used to countdown to the date your baby is due and work just like any other countdown timer.

To look for countdown clocks for your MySpace profile go to Google and search for MySpace countdown timers, there will be many to choose from with different designs, text fonts, animations, colors and sizes, when you have found one that best matches your profile layout enter the widget code in the section you would like to place the widget.

Sharing music

Another great feature of MySpace is the music sharing facility, this enables you to search for a band on MySpace and then select a song to add to your profile page, when a visitor looks at your profile the song will play in the background automatically if it is set to do so in the options of your profile.

Bands can also set up profiles for there band and upload there music in mp3 format for users to add to there profile, this is a great way of getting your band noticed.
