[tex] \cos(45 - x) \times \cos(x) - \sin(45 - x) \times \sin(x) [/tex]
Answer:
√2/2
Explanation:
cos(45 - x)cos(x) - sin(45 -x)sin(x)
Using trigonometric identities,
cos(A - B) = cosAcosB + sinAsinB where A = 45 and B = x. So,
cos(45 - x) = cos45cosx + sin45sinx
= (1/√2)cosx + (1/√2)sinx (since sin45 = cos45 = 1/√2)
Also,
sin(A - B) = sinAcosB - cosAsinB where A = 45 and B = x. So,
sin(45 - x) = sin45cosx - cos45sinx
= (1/√2)cosx - (1/√2)sinx (since sin45 = cos45 = 1/√2)
So.
cos(45 - x)cos(x) - sin(45 -x)sin(x) = [(1/√2)cosx + (1/√2)sinx]cos(x) - [(1/√2)cosx - (1/√2)sinx]sin(x)
= (1/√2)cos²x + (1/√2)sinxcos(x) - [(1/√2)sinxcosx - (1/√2)sin²x]
= (1/√2)cos²x + (1/√2)sinxcos(x) - (1/√2)sinxcosx + (1/√2)sin²x
= (1/√2)cos²x + (1/√2)sin²x
= (1/√2)[cos²x + sin²x]
= (1/√2) (since cos²x + sin²x = 1)
= 1/√2 × √2/√2
= √2/2

____ is a technology used in WLAN in which sending and receiving devices have multiple antennas and transmit data over multiple streams to send data faster with few errors.
Answer:
multiple input multiple output (MIMO).
Explanation:
Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.
Generally, the most commonly used electromagnetic wave technology in telecommunications is radio waves.
Radio waves can be defined as an electromagnetic wave that has its frequency ranging from 30 GHz to 300 GHz and its wavelength between 1mm and 3000m. Therefore, radio waves are a series of repetitive valleys and peaks that are typically characterized of having the longest wavelength in the electromagnetic spectrum.
Basically, as a result of radio waves having long wavelengths, they are mainly used in long-distance communications such as the carriage and transmission of data.
In Radio transmission and Networking, multiple input multiple output (MIMO) is a type of technology used in a wireless local area network (WLAN), in which both the sending (transmitter) and receiving (receiver) network devices have multiple antennas and are able to transmit data over multiple streams in a bid (effort) to send data faster with little or fewer errors and gain knowledge of the communications channel.
A user carries a laptop between a home network and a business network. While on the business network the user requires a static IP (Internet Protocol) address. When at home, DHCP (Dynamic Host Configuration Protocol) is used to obtain an address.

You are configuring a wireless access point for the office you work in. You are configuring both 2.4 GHz (Gigahertz) and 5 GHz for users. Which wireless standard will only use the 5 GHz spectrum
The wireless standard that uses only the 5 GHz spectrum is IEEE 802.11ac. It is a faster and more recent standard than IEEE 802.11n, which can use both 2.4 and 5 GHz spectrums.
The 2.4 GHz spectrum is a lower frequency than the 5 GHz spectrum and has a longer wavelength, which means it can better penetrate walls and other obstacles. However, it also means that there is more interference from other devices that use the same spectrum, such as microwaves and Bluetooth devices. The 5 GHz spectrum, on the other hand, has a shorter wavelength and is less likely to be affected by interference but has a more limited range. Wireless standards such as IEEE 802.11n and IEEE 802.11ac are developed to take advantage of the properties of different frequency spectrums to provide faster and more reliable wireless connections.
