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 we need to orient entire set up in magnetic meridian before performing experiment?
Orienting the setup in the magnetic meridian helps ensure accuracy in experiments involving magnetic fields because it aligns the equipment with the Earth's magnetic field. This alignment reduces interference from external magnetic fields and produces more reliable results.
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 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 a merdian?
A meridian is an imaginary line that runs from the North Pole to the South Pole on the Earth's surface. It is used in navigation and to indicate longitude. The prime meridian, at 0 degrees longitude, passes through Greenwich, England.
What is the set of contacts actuated by magnetic coil?
Relay
Is there any way to set up a magnetic field other than by causing charges to move?
Yes, magnetic fields can also be created by permanent magnets. These magnets produce a magnetic field due to the alignment of their magnetic domains within the material.
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.
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.
What is the procedure of magnets?
To make a magnet, a material with magnetic properties, such as iron or steel, is exposed to a magnetic field. This aligns the magnetic domains within the material, creating a permanent magnetic field. The material is then cooled or left in the magnetic field to "set" the alignment, making it a magnet.
Is Jamaica west or east of the prime meridian?
Since the earth is a sphere, you could reach Jamaica from the Prime Meridian in either direction.But your trip would be a lot shorter if you set out to the west.Jamaica extends between about [ 76.2° -- 78.3° ] west longitude.
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.
