The area of the rectangle is infinite because the length of the sides is undefined.

Replacing heating element in Kenmore model 110.65922


The heating element will have multiple coils to it with two leads coming into it. POS/NEG. If that is it then it is very strange that it is not enclosed in some way shape or form.

Integrate equations, using 0 and .123 as limits


Set Input/output to MathIO.
Press the Integrate key, to the right of CALC.
The image of integral appears with a rectangle for the function, and two small squares (one for the upper limit the other for the lower limit).

Type in the integrand (the expression you want to integrate) in the bigger (on your display) rectangle. Use appropriate parenthesis. To type in X press [ALPHA] )
Use the down arrow to move cursor to the square for the lower limit. Type in the lower limit. Use the Up arrow to move cursor to the upper limit square. enter the upper limit. Press [=] key. If you did not make mistakes, and your expression is not too complicated you should get your integral.

Don't have the directions to put evenflo exersaucer together, need help. Is there somewhere I can get the directions? reg. number 07T-0538604


Instructions
    • 1 Place the large, round base on the floor. The outwardly curving edge should be facing downward.
    • 2 Attach the three pedestals to the base. To do so, insert your finger into each pedestal and loop the spring within around the hook found on the base in the appropriate holes. Insert the three plastic tabs on each pedestal into the base, locking them into place.
    • 3 Press the wider end of a lower leg assembly onto each pedestal piece. By wiggling the lower leg assembly side to side, you will eventually snap the pieces into place.
    • 4 Hold the seat ring in your lap with the open edge facing upward. Press each of the six wheels into the wheel holders around the edge of the seat ring. Each wheel will snap into place when positioned correctly.
    • 5 Insert the cloth seat into the seat ring, aligning the diamond on the cloth seat with the triangle on the seat ring. Each plastic tab lining the edge of the cloth seat attaches to a peg on the seat ring. Snap these connections into place.
    • 6 Hold the Exersaucer tray on its side and press the seat ring into the center. Once the seat ring snaps into place, it should be able to spin in place.
    • 7 Attach the three spring caps to the Exersaucer tray. These spring caps cover the three large holes in your tray, and are attached by a firm clockwise twist.
    • 8 Attach the upper leg assemblies to the upper leg crowns. These crowns act as the "socket" and the upper leg assemblies act as the "ball." By pressing them together with a click, the upper leg assemblies can twist and rotate in place.
    • 9 Turn the tray upside down and press each upper leg crown base into the round holes in the tray with a firm twist. Each upper leg crown features a height adjustment hole, which will face outward when properly attached.
    • 10 Turn over the tray so that the upper leg assemblies are facing downward. Insert each upper leg assembly into a lower leg assembly, being sure to pull away the height adjustment tab to allow the assemblies to slide together.
    • 11 Press each toy into its respective port on the surface of the tray. The toys each have a distinct base, which clicks into the correspondingly shaped tray port

Is a rectangle squared or cubed


Hello,
Some wires got crossed here. A cube is a solid (a 3D object), whereas a rectangle and a square are 2D figures. You cannot compare a 2D figure with a 3D figure any more than you can compare say a parking lot and a highrise building.

A rectangle is a quadrilateral (closed polygon with 4 sides). In a rectangle, opposite sides are parallel and equal in length. In a rectangle all 4 angles are equal, each measuring 90 degrees.
All this is true for a square, except that all sides are now equal. So you can say that a square is a special kind of rectangle, namely, a rectangle with equal sides.
Hope it helps.

I have a Phillips 42 inch plasma T.V. The lower half of the screen will randomly go black.With a whack to the left middle of the unit the situation is resolved.I also have a continued set of colored lines...


I wanted to share my solution to this problem. Not only is it an easy fix (aside from taking the tv apart) but it also explains some of the strange methods I've read that have worked, such as taking out padding from behind the boards or putting a magazine under one side and even tapping on the tv for a temporary fix.

Granted its only been a few days of it working but I tell you this....It's not done the half black screen once! And trust me when I say it was doing it constantly.

Ok so first off the problem definitely lies in the upper/lower buffer boards. On the model mentioned by the OP (same model I have) it's located on the same side as the power button (right side when you are looking at the tv).

Ok so you've got the tv openned face down on a non static surface. Btw I was shocked at how many youtube videos I found of ppl working on their tvs while its laid flat on their sofas!

When you are looking into it you will see on one side there are two vertical boards hooked up to another board more towards the center. These two boards are your upper and lower boards that provide the upper and lower picture. The problem I was having was in the lower section of the tv going black so obviously that corresponded to the lower board. (They are labelled upper and lower if you look closely)
So here is what I did:

I noticed the lower board was not sitting flush so I unscrewed the one screw on the bottom and noticed how much of a gap was in the screw hole. The problem was it was screwed down in such a way that one of the connections going to the main board was not making it's proper connection. So I just gave it a little push towards the center, held it, and screwed it back down.

That's it! It's fixed now. No need for replacing anything. Just poorly drilled holes and a few things not lining up correctly!

So hopefully anyone else that's having this same problem might have some luck in using this fix. Good Luck!
