When should we use either the sine or cosine function in statics analysis?

In statics analysis, we use the sine function when dealing with forces that are perpendicular to a reference axis, and the cosine function when dealing with forces that are parallel to the reference axis.


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.


How can a force be resolved in to rectangular components?

You would use trigonometry for that. If, for example, you have a force of magnitude 10 at an angle of 30 degrees: * The x-component is 10 times the cosine of 30 degrees * The y-component is 10 times the sine of 30 degrees Or better yet, learn to use the polar-->rectangular conversion on your scientific calculator.


How do i find the components of a vector?

Usually the two familiar components are opposite and adjacent. For opposite sine function and for adjacent cosine function have to used. Hence as R is to be resolved then the components are R sin@ and R cos@, where @ is the angle of R with its adjacent.


What does a sine curve represent in physics?

In physics, a sine curve is used to represent periodic phenomena such as simple harmonic motion or alternating current. It shows how a quantity varies sinusoidally with time or distance. The amplitude, frequency, and phase of the sine curve provide important information about the behavior of the system being studied.

What are the Differentiate the sine wave and cosine wave?

The differential of the sine function is the cosine function while the differential of the cosine function is the negative of the sine function.


When to use sin and cos.?

The sine and cosine were originally developed for use in surveying. They provided a way to measure the distance across lakes and around mountains. Soon they were found to be useful in navigation. The sine was used to calculate pi. When electrical measurements were made, the sine law was used. If you want to know when to use the sine and when to use the cosine, you will need to get a trig book, a physics book, an astronomy book, a sailing book, and a few other books and read them all.


How does the tangent function relate to sine and cosine?

Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.


Why are sine and cosine functions used to describe periodic?
