Homework Statement
y= l sin x l < absolute value of sinx
Homework Equations
The Attempt at a Solution
y= l sin x l= sinx, if x>0
-sinx, if x< 0
0, if x=0
I get that part, but when i draw the graph I don't get it
What about the graph don't you get?Cudi1 said:Homework Statement

Not necessarily. The graph is reflected across the x-axis when sin(x) < 0, which happens when -pi < x < 0, or when pi < x < 2pi, and a bunch of other intervals.Cudi1 said:k got it, so when x<0 it gets reflected across the x axis
That's how you need to look at it. It's not just when x >= 0 or x < 0.Cudi1 said:, for the other values since we are dealing with absolute value, an aboslute value of a negative is positive. Thanks, only reason I got confused is when you put it in from sinx, if sinx>=0 and when sinx<0 thanks
The equation "Y= l sin x l < absolute value of sinx" represents the absolute value of the sine of x being less than Y. This means that the output value of the sine function will always be a positive number less than Y.
To graph this equation, you would start by plotting the points of the absolute value of sinx, which will create a V-shaped curve. Then, you would plot the line y=Y, which will act as a horizontal boundary. The region between the two graphs represents the solutions to the inequality.
The solutions to this inequality are all values of x that fall within the region between the absolute value of sinx and the line y=Y. This means that the solutions can be any value of x that falls within the V-shaped curve, as long as it is below the horizontal line y=Y.
This equation can be used in science to represent relationships between variables. For example, it can be used to describe the behavior of a pendulum or the amplitude of a sound wave. It can also be used to analyze data and make predictions in various scientific fields such as physics, biology, and engineering.
The absolute value in this equation ensures that the output value of the sine function is always positive, regardless of the input value of x. This is important because it allows us to more accurately represent the behavior of the sine function and its relationship with Y. It also helps to simplify the graphing and analysis of the equation.
