The answer is Square root of 2. ( trignometric problem - ef5590434a387b3c4427e09d5b08baaf.png )
They way it works is :
sec theta at 45 degre is 1 over cosine of theta or
cosine of theta is square root of 2 over 2.
Therefore you have 1 over square root of 2 over 2.
After rationalization and simplification you should have .

I have come to use my Cintiq 21 ux on a win7 x64 system with a twin firepro V5800 graphics card. My Mac 21" screen is fine but the Cintiq goes green when not receiving a signal and the green shows like...


The output from the graphics card may not be compatible with the screen. I would try to verify that first. Next look for any bad connections. Distortion to that degree in many cases is cased by a bad cable, connector, or just not being plugged in correctly.

I hope this doesn't sound stupid. Have you tried going into the settings for the tablet, and changing them around. It should give you a choice whether you want the mouse finder 'ring'. And give you a choice what you want for the pen pressing, buttons, and more.

The built in mouse pad needs cleaning. How can the panels be opened ?


I experienced the same issue but luckily enough one of my close friends is a Sony tech and helped me with this (and saved me much money too!)
You need to remove the back panel and soak the unit in lukewarm water. Be sure that the water temp. does NOT exceed 75 degrees or you will damage the battery. Soak for not more than 10 minutes. If no results, then remove the back panel again and soak it for 15 minutes. Again, DO NOT immerse the unit in water that is warmer than 75 degrees!

My wacom graphire 4 stylus is malfunctioning


In the Control Panel for the pen, hold down CTRL (PC) or ALT (Mac) and click on the About button to open the diagnostic screen. Look at the value for "Pressure" on the right hand side - this should stay at 0 until the pen is brought into contact with the tablet.
If it shows a high value (above 50), then you pen may be defective and, if in warranty, will be replaced. A half hour ago, my pen gave a value of 220 and, being well out of warranty, cannot be replaced for free. However, it now gives a value of 0 and works perfectly. The solution? I bashed it (side on) on the table top and against the flat of my hand for about 10 minutes as per a low-tech solution on the Wacom-Europe forum. With each series of smacks, the pressure fell toward 0. If you can't get it below about 60, it may still be okay as there is a pressure offset control in the diagnostic panel that goes up to 59.
Good luck! Alastair.

G-Pen F610 versus Photoshop 7


I believe I understand what you are referring to. I can reproduce this same effect in Photoshop 6. The settings for tweaking this and other options like opacity is under the "BRUSH DYNAMICS" button for the particular brush. The default seems to have SIZE set to be managed by the STYLUS pressure. If this is changed to OFF, the size will remain constant, and you can use stylus pressure to change another dynamic. Hope this is of some help.

Graphire4 Tablet not reading pen


If you are on a Windows Vista machine, you need to delete your preference files for your tablet driver. The issue you are experiencing is likely due to a corrupt prefs file, which in my case was what caused the problems specifically in photoshop.

2 mouses on screen with Vista!?


I posted earlier, but found a solution so I thought I would let other users know. Forget the Adesso drivers. Download and install the driver for the Aiptek 12000U Hyperpen tablet. They are the same tablet and apparently Aiptek has figured out the Windows vista issue. You can find the drivers here:
