Why you are considering sine wave as ac but not cosine wave?
Sine wave is considered as the AC signal because it starts at 0 amplitude and it captures the alternating nature of the signal. Cosine wave is just a phase shift of the sine wave and represents the same signal. So, either sine or cosine wave can be used to represent AC signals. However, sine wave is more conventionally used.
What is the principle of dichotomy?
The principle of dichotomy states that every proposition can be either true or false, but not both. It is a fundamental concept in classical logic, where statements are categorized as either being true or false. This principle forms the basis for logical reasoning and analysis.
What is a function machine?
The function of a microfilming machine is to either capture an analog image (Camera) or print an analog image (COM Recorder) onto a microform.
What components of time series analysis refers to the long-term tendency of the data to be either increasing or decreasing?
Trend analysis in time series refers to the long-term tendency of the data to increase or decrease. This component helps identify overall patterns or movements over time, which can be crucial for making forecasts and understanding underlying changes in the data.
What is part of speech for damage?
The word "damage" can function as either a noun or a verb. As a noun, it refers to harm or injury caused to something. As a verb, it means to harm or impair something.
What is the derivation of the wave function?
A simple wave function can be expressed as a trigonometric function of either sine or cosine. lamba = A sine(a+bt) or lamba = A cosine(a+bt) where lamba = the y value of the wave A= magnitude of the wave a= phase angle b= frequency. the derivative of sine is cosine and the derivative of cosine is -sine so the derivative of a sine wave function would be y'=Ab cosine(a+bt) """"""""""""""""""" cosine wave function would be y' =-Ab sine(a+bt)
What is a reciprocal trig function?
A reciprocal trigonometric function is the ratio of the reciprocal of a trigonometric function to either the sine, cosine, or tangent function. The reciprocal of the sine function is the cosecant function, the reciprocal of the cosine function is the secant function, and the reciprocal of the tangent function is the cotangent function. These functions are useful in solving trigonometric equations and graphing trigonometric functions.
When is it better to use the sine function and when is it better to use the cosine function when modeling sinusoidal behavior?
The only difference is a phase shift of pi/2 radians (90 degrees), so there is no aprticular advantage in either.
Which angle length does cosine give you?
Sides have lenght, angles do not. Cosine is the ratio of the adjacent side to the hypotenuse. Cosine can be used to find either of these sides if the other is known.
How do you know when to use sine over cosine or cosine over sine?
You can choose either or but tangent which is sin/cos seems to be the most common way.
How do you find out the top angle of an Isosceles triangle if you do not know the base angle?
It depends on whether you know the lengths of all three sides (either explicitly or otherwise). If you don't know the lengths of the sides you cannot find the top angle. If you do know the sides you can apply the cosine rule: cos(A) = (b2 +c2 - a2)/2bc and then use the inverse cosine function to determine A.
When finding the sides and angles of a right triangle when is it necessary to use Trigonometry?
if you have any two sides, you can calculate either of the (non right angle) angles. if you have a (non right angle) angle and one side, you can calculate any other side. you will need either tables, or a scientific calculator with sin / cosine / tangent function
Can cosine graphs continue infinitely in either direction?
Yes!!!! They are cyclic in nature. The cosine wave goes from negative infinity to positive infinity. It has a Wavelength of 2pi(360 degrees) and ranges from -1 to +1 . Similarly the Sine wave.
How do you find the length of a side in a triangle that is not a right triangle?
Use either the Sine or Cosine rules depending on the information you know about the triangle.
How does knowing the zeros of a function help determine where a function is positive?
Knowing the zeros of a function helps determine where the function is positive by identifying the points where the function intersects the x-axis. Between these zeros, the function will either be entirely positive or entirely negative. By evaluating the function's value at points between the zeros, one can determine the sign of the function in those intervals, allowing us to establish where the function is positive. This interval analysis is crucial for understanding the function's behavior across its domain.
What is picards theorem?
In complex analysis, the term Picard theorem (named after Charles Émile Picard) refers to either of two distinct yet related theorems, both of which pertain to the range of an analytic function.
What is partial analysis?
Partial analysis is simply a first view of how something is going. This is an observation done either briefly or less thoroughly than a complete analysis.
