Graph of the tangent function The graph of tangent is periodic meaning that it repeats itself indefinitely. As you can see the tangent has a period of π with each period separated by a vertical asymptote.

The graph of y sintheta has a maximum value of 1 and a minimum value of -1.
Graph of tangent function. To plot the parent graph of a tangent function f x tan x where x represents the angle in radians you start out by finding the vertical asymptotes. Y -intercept. More References and Links to Graphing Graphing Functions Tangent Function.
Find the vertical asymptotes so you can find the domain. If youre seeing this message it means were having trouble loading external resources on our website. 0 0 x.
Those asymptotes give you some structure from which you can fill in the missing points. Tan θ sin θ cos θ cot θ cos θ sin θ. Placing trigonometric values like this against the angle produces a tan graph.
The tan graph is the graphical representation of the function tan x. Sal draws the graph of the tangent function based on the unit circle definition of the function. The tangent function has asymptotes where the cosine is zero.
Have the same curve only shifted along the x-axis. The sine and cosine graphs are very similar as they both. The tangent function fx a tanb x c d and its properties such as graph period phase shift and asymptotes are explored interactively by changing the parameters a b c and d using an applet Free Maths Tutorials and Problems.
The name of the tangent function comes from the tangent line that is perpendicular to the radius and intersects the circle at a single point. To graph the tangent function we mark the angle along the horizontal x axis and for each angle we put the tangent of that angle on the vertical y-axis. Properties of the Tangent Function y tan x.
The result as seen above is rather jagged curve that goes to positive infinity in one direction and negative infinity in the other. An asymptote is an indication of a place where the function is undefined. The tangent of an angle is designed against that angle measure to produce the tan graph.
On the x axis we have the. To create a tangent segment draw a line perpendicular to the x-axis and then extend θ so it intersects the tangent line. Tan 0 0 as the opposite side would have zero length regardless of the length of the adjacent side.
The Tangent function has a completely different shape. The graph of a tangent function y tan x is looks like this. It goes between negative and positive Infinity crossing through 0 and at every π radians 180 as shown on this plot.
Tangent and Cotangent Graphs. The graph has a period of 360. From the definition of the tangent and cotangent functions we have.
The tangent function is defined as the length of the red segment. X ℝ x π 2 n π where n is an integer. The concept of amplitude doesnt really apply.
Graph of tangent function The formula for this graph is simply ytan x. Now consider the graph of. Going back to SOH CAH TOA trig with tan x being opposite adjacent you can see that.
For graphing draw in the zeroes at x 0 π 2π etc and dash in the vertical asymptotes midway between each zero. Sal draws the graph of the tangent function based on the unit circle definition of the function. The domain of the tangent function is all real numbers except whenever cos θ0 where the tangent function is undefined.
On the y axis we have the traditional number line with positive numbers and negative numbers. Tangent graphs The graph of y tan x is an odd one - mainly down to the nature of the tangent function. Graph of Tan Function.
Plot of the Tangent Function. Tan 52 8265 18. Cos theta 0 cosθ 0.
Unlike sine and cosine however tangent has asymptotes separating each of its periods. At π 2 radians 90 and at π 2 90 3 π 2 270 etc the function is officially undefined because it could be positive Infinity or negative Infinity. Trigonometric graphs The sine and cosine graphs.
This means that it repeats itself every 360. Then draw in the curve.
