What are the domains of sine cosine and tangent?
The domain of a function is the set of values of the independent variable for which the function is valid. In practice, this is the allowable values of X or, in this case, theta. The sine and cosine functions have a domain of all numbers from negative infinity to positive infinity. The tangent function, however, is sine(theta) / cosine(theta). Cosine(theta) has value of zero at theta equal to pi / 2, 3pi/2, 5pi/2, ... in the positive direction, and -pi/2, -3pi/2, -5pi/2, ... As a result, tangent(theta) is undefined at these values, so the domain of tangent is all numbers from negative infinity to positive infinity except all numbers n pi/2 where n is odd.
What are the possible values of k for which the line of y equals x -8 is tangent to the curve of y equals 4x squared plus kx plus 1 showing work?
Since the curves are tangent, they have the same slope at that point and the same x and y value at that point. Set equations equal and set slopes equal and solve Togetslope, you need to know calculus first derivative slope of one equation is dy/dx = 8x +k and the othereqaution slope is dy/dx = 1 so youhave 4x^2 + kx + 1 = x -8 8x + k = 1 4x^2 +kx -x + 9 = 0 8x + k -1 = 0 solve for k k ==-11 or +13
How was the meter defined in 1971?
Until 1983 the metre was defined at one ten millionth of the distance from the equator to the north pole. That definition has changed to reflect greater understanding and knowledge. Originally, the meter was based on the distance between the equator and the north pole along the meridian that went through Paris. That distance was set at 10,000 kilometers and the metre was ten millionth of the distance.
What is the set of every set?
the set of every set is that set
What is a mull set?
'Mull Set' . I think you mean 'NULL SET'. This means a set with no elements, or an empty set.
Why do you need to set a galvanometer to 0?
Zero is the normal position of the galvanometer when there is no detection in process.
What is a merdian?
A meridian is a constant longitude circle passing at a given place. The meridian in Greenwich is also called the Prime Meridian which is set at zero longitude.
What is a stable galvanometer?
When current is passed throgh a galvanometer, the coil oscillates about its mean position before it comes to rest. To bring the coil to rest immediately, the coil is wound on a metallic frame. Now, when the coil oscillate, eddy currents are set up in the metallic frame, which opposes further oscillations of the coil. This inturn enables the coil to attain its equilibrium position almost instantly. Since the oscillation of the coil die out instantaneously, the galvanometer is called dead beat galvanometer.
How many meridians are in the eastern hemisphere?
There are 180-meridians in the eastern hemisphere. The meridian through Greenwich, England, also called the Prime Meridian, was set at zero degrees of longitude. The meridian on the opposite side of the earth is 180-degrees.
What is the set of contacts actuated by magnetic coil?
Relay
Where is the compass arrow always set?
It automatically points to magnetic north unless it is influenced by some other magnetic source.
Are all ductile metals magnetic?
No, not all ductiles possess true magnetic properties. The main set of "magnetic" elements (not including those with paramagnetic or partial magnetic properties) are: iron, nickel, and cobalt For example, copper is very ductile, but is not magnetic.
Is a leapfrog fridge farm magnetic animal set sold in stores?
A leapfrog fridge farm magnetic animal set is sold in stores. Someone can acually go in stores and buy a leapfrog fridge farm magnetic animal set or they can go online, looking for a trusted business site and order one from home.
Is there any way to set up a magnetic field other than by causing charges to move?
No, the present physics states that moving charges relatively is the only way to set up a magnetic field.
Can you determine how much time does it take for magnetic line of forces to set up in space?
You cannot determine how much time it takes for magnetic line of forces to set up in space. It is not considered a real thing.
Where is the Prime Meridien?
The Prime Meridian, also called the Greenwich Meridian, is 0 degrees longitude. The observatory where the Meridian is defined is in Greenwich, England. The line passes from the North Pole through England, Europe, Africa, and ends at the South pole in Antarctica. Opposite the Prime Meridian is the International Date Line, or the Ante-Meridian. The choice of the Meridian is entirely abitrary. At various time the Meridian has been set at other locations. The US even used Washington, DC, as the Prime Meridian. Standardization was important for global navigation, so it was finally agreed to use Greenwich as the meridian "0" reference. This is especially convenient because the Ante-Meridian dateline is located where there are no large land masses.
Where can the Leapfrog Fridge Farm Magnetic Animal Set be purchased?
The Leapfrog Fridge Farm Magnetic Animal Set can be purchased from Amazon, ToysRus, Ebay and many other sellers. It can also be purchased directly from the manufacturer Leapfrog.
