y = sin x, or y = cos x etc. can be graphed by making a table of values. The x column in the table would be angle measurements (usually in degrees or radians) and the y column would be the trig. function value. Then plot the points and sketch the curve going thru those points.
Ex: for y = sin x
x , y
0 0
30 0.5
45 0.707
etc and then graph these

What is the zero of a function and how does it relate to the functions graph?
A zero of a function is a point at which the value of the function is zero. If you graph the function, it is a point at which the graph touches the x-axis.
How is the function differentiable in graph?
If the graph of the function is a continuous line then the function is differentiable. Also if the graph suddenly make a deviation at any point then the function is not differentiable at that point . The slope of a tangent at any point of the graph gives the derivative of the function at that point.
Recall that the vertical line test is used to check whether a particular graph represents the graph of a function what are correct statements for this graph?
This graph fails the vertical line test at x = 3This graph is not the graph of a function.
When can a graph represent a function?
A graph represents a function if and only if every input generates a single output.
Is an oval a graph of a function?
No, the graph of an oval/ellipse is not a function because it does not pass the vertical line test.
What is a graph that shows how two related sets of data that change over time?
trigonometry
What is the sgn function in trigonometry?
The sign function is used to represent the absolute value of a number when used in trigonometry. It is also referred to as the signum function in math.
What is the frequency in maths?
How often a graph repeats itself; this is used often in trigonometry.
Is a circle graph a function?
No, a circle graph is never a function.
What is the zero of a function and how does it relate to the functions graph?
A zero of a function is a point at which the value of the function is zero. If you graph the function, it is a point at which the graph touches the x-axis.
How do nurses read heart beats using trigonometry?
Trigonometry helps nurses read the heart beats on an EKG because an EKG shows the heartbeats in a graph.
Can you explain what the function of trigonometry is?
The understanding of shapes and angles.
What is C in trigonometry?
usually referred as the function COS
Is trigonometry a function or ratio?
Neither, it is a mathematical discipline.
How can you tell if a graph is a sine function or a cosine function?
sine graph will be formed at origine of graph and cosine graph is find on y-axise
Can a line be a graph of a function?
Yes the graph of a function can be a vertical or a horizontal line
Can a line be the graph of a function?
Yes the graph of a function can be a vertical or a horizontal line
