The fraction is 2/8, which can be simplified, if required.
If you've ever flown then you used complex numbers. The basic equation w=z+1/z is used to design air foils (airplane wings). While you don't actually concern yourself with these equations anymore than the thermodynamic equations that govern the running of your car's engine. Check out the related link for some interesting application of imaginary and complex numbers, though.
As with many other topics of advanced math, it depends whether your "real life" includes working in some engineering area, or not. If you work in electrical engineering or electronics, you will use complex numbers on a daily basis; similarly if you do a lot of math for some reason.Complex Numbers (ones involving the imaginary unit 'i' which is defined to handle the square root of -1) are a convenient way to describe the behavior of some electric circuits and waves.One thing you may encounter in your 'real life' are uninterruptible power supplies (UPS - what keeps your computer running when the power goes out). You will see ratings such as 500 VA / 300 W. This has to do with Complex Power. Electric circuits, which have inductances (such as transformers and electric motors) or capacitors, behave in a way that is described by complex numbers. While Volts X Amps equals Watts, the 300 W is the 'real power' (the amount available to do work), and the 500 VA is the apparent power (the total power that the power supply is capable of producing). The reactive power (due to capacitance & inductance) is represented by the imaginary component and it is at right angles to the real power (represented by the real component).Another use of complex numbers is in the Fast Fourier Transform (FFT) - one of the most ubiquitous algorithms - used heavily for signal processing. If you have a digital camera, a cell phone, an LCD - FFT is there, bringing complex numbers along.The complex equation w=z+1/z is a basic formula used for designing air foils-airplane wings and Figuring out flow forces around a circular object in water for instance.Please see the related links for details.
6/12 of the ducks have blue wings
that ducks have wings =)
Not really. Ducks have wings not arms.
Cormorants and Anhingas do not have the natural oils like ducks do that repel water. Therefore, they can get waterlogged so they spread their wings to dry them afer swimming.
Ducks defend themselves by using their strong bills to bite or peck at predators, as well as by flapping their wings or swimming away quickly. Some ducks also have the ability to make loud quacking sounds or to fly away to escape danger.
Cos they have wings
Yes, ducks are capable of diving underwater to forage for food. They use their webbed feet to paddle and their wings to help maneuver while swimming. Some duck species, like the diving ducks, are particularly skilled at diving and can stay submerged for up to 30 seconds.
Flapping wings and quacks
no female bird of any species loses their wings.
All ducks can fly, even domestic ones.
Ducks do not flap their wings
Ducks waddle due to their unique leg anatomy, which is set farther back on their bodies. This waddling gait helps them maintain balance and stability while walking on land. Additionally, their short legs and webbed feet are more suited for swimming than walking.
