How Do You Differentiate K sin(Gx + 5)?

In summary, differentiating K sin(Gt + 5) allows us to find the instantaneous rate of change of the function at any given point, helping us to understand its behavior and properties. To differentiate the function, we use the chain rule where K and G are constants. The constant K in the function represents the amplitude or height of the sine wave, and can be negative, resulting in a reflection of the graph over the x-axis. The value of G determines the frequency of the sine wave, with a larger value resulting in a higher frequency and a smaller value resulting in a lower frequency.

Homework Statement



if y = K sin(Gx + 5)

what is dy/dx

Homework Equations



y=sin x

dy/dx = cos x

The Attempt at a Solution



y = K sin(Gx + 5)

dy/dx = KG cos (Gx +5) (1)

or

dy/dx = KG cos GX + 5 (2)


i think it is (1)

is this correct or it is non of these (other)?

Why would you think it is (2) in the first place?
(1) is certainly correct, but your doubt indicates you are not quite familiar with the rules of differentiation yet.

1. What is the purpose of differentiating K sin(Gt + 5)?

The purpose of differentiating K sin(Gt + 5) is to find the instantaneous rate of change of the function at any given point. This can help in understanding the behavior and properties of the function.

2. How do you differentiate K sin(Gt + 5)?

To differentiate K sin(Gt + 5), we use the chain rule where K and G are constants. The derivative of sin(Gt + 5) is cos(Gt + 5) and the derivative of Gt + 5 is G. Therefore, the overall derivative is K cos(Gt + 5) * G, which can also be written as KG cos(Gt + 5).

3. What is the significance of the constant K in the function K sin(Gt + 5)?

The constant K in the function K sin(Gt + 5) represents the amplitude or height of the sine wave. It determines how high or low the graph of the function will be on the y-axis.

4. Can the value of K be negative in K sin(Gt + 5)?

Yes, the value of K can be negative in K sin(Gt + 5). This will result in a reflection of the graph of the function over the x-axis. The negative value of K will change the direction of the sine wave from upwards to downwards.

5. How does the value of G affect the graph of K sin(Gt + 5)?

The value of G in K sin(Gt + 5) determines the frequency or the number of cycles of the sine wave in a given interval. A larger value of G will result in a higher frequency, meaning more cycles in a given interval, while a smaller value of G will result in a lower frequency, meaning fewer cycles in a given interval.
