1 answer:
igomit [66]4 years ago
4 0

Answer:

e^{ix} = cosx + i sinx

Explanation:

In mathematics, Euler's formula is an equation in complex analysis, that gives a relationship between an exponential factor and the trigonometric functions.

The Euler equation is:

e^{ix} = cosx + i sinx

Here,

e - base of the natural logarithm

i - imaginary unit

x - argument given in radians

sin , cos - trigonometric functions sine and cosine respectively.

Ray Of Light [21]

Answer:

The correct answer is C. World Coordinate System

Explanation:

The World Coordinate System has to do with that coordinate system which is fixed in the activities of the CADing. There is a default system in which we can refer to them as soon as we want to manipulate the objects and add new elements.

Define denial and identify three of your own examples of denial (they can be from your own life or someone else's). In 300 words
Fantom [35]

Answer:

Denial is a defense mechanism which allows an individual not to accept the truth about a painful experience or distress.

Explanation:

Denial is a way of coping with distress. Denial means trying to reject the truth about a situation. It could be denying the truth about your personal situation or about someone else like your friends, parents or siblings.

Denial is a defense mechanism used to protect oneself against accepting a painful experience or situation in life.

Denial could be helpful or harmful.

It can be helpful when one begin to take action about a problem by seeking for help.

It could be harmful if you don't seek for help when in distress.

A person engaged in denial is trying to stay sane and act normal like everything is alright with he/she. The person tries to block negative thought and focus on more positive thoughts.

Example of denial

1) A young lady who just experienced a breakup from her boyfriend who she truly loves but act like the breakup doesn't affect her or that she doesn't love the guy.

2) A 21 year old person who has cancer and has about 10 months to live have plans of celebrating his/her 25th birthday in a big way

3) When someone is harboring the thought that coronavirus is not real or it is not a serious disease.

What is the voltage across the load, RL, in
JulsSmile [24]

Answer:

  (c)  5.71 V

Explanation:

The circuit can be redrawn to a Thevenin equivalent that is 6V through a 5-ohm resistor into a 100-ohm load. Then the voltage at the load is ...

  (6 V)(100/(100 +5) ≈ 5.71 V

Identify the unit of the electrical parameters represented by L and C and prove that the resonant frequency (fr)=1÷2π√LC
Gre4nikov [31]

Answer:

L = Henry

C = Farad

Explanation:

The electrical parameter represented as L is the inductance whose unit is Henry(H).

The electrical parameter represented as C is the inductance whose unit is Farad

Resonance frequency occurs when the applied period force is equal to the natural frequency of the system upon which the force acts :

To obtain :

At resonance, Inductive reactance = capacitive reactance

Equate the inductive and capacitive reactance

Inductive reactance(Xl) = 2πFL

Capacitive Reactance(Xc) = 1/2πFC

Inductive reactance(Xl) = Capacitive Reactance(Xc)

2πFL = 1/2πFC

Multiplying both sides by F

F * 2πFL = F * 1/2πFC

2πF²L = 1/2πC

Isolating F²

F² = 1/2πC2πL

F² = 1/4π²LC

Take the square root of both sides to make F the subject

F = √1 / √4π²LC

F = 1 /2π√LC

Hence, the proof.
