Algebra 2 asymptotes and intercepts of trig functions worksheet

Tangent and secant blow up where cosine is zero, at π/2 plus every π; cotangent and cosecant where sine is zero, at every π. Sine crosses the axis at every π and cosine at π/2 plus every π. With bx inside, divide every one of those by b: the first one moves, and so does the spacing.

How to do these

$y = \tan (3 x)$ : where is the first asymptote to the right of the $y$ -axis, and how far apart are the asymptotes?

tan is undefined where 3x = π/2, so x = π/6.
Asymptotes of tan are π apart, so here they are π/3 apart.

The answer is $x = \frac{π}{6}$ , every $\frac{π}{3}$ .

Where students go wrong

Forgetting to divide by b. The asymptotes of tan(3x) are three times as close together as those of tan x.

Also called vertical asymptotes of tangent, zeros of sine and cosine, period and asymptotes or trig graph features.

What you can put on this worksheet

Where the asymptotes are: $y = \sec (3 x)$ : where is the first asymptote to the right of the $y$ -axis, and how far apart are the asymptotes? → $x = \frac{π}{6}$ , every $\frac{π}{3}$
Where the x-intercepts are: $y = \cos (3 x)$ : where is the first $x$ -intercept to the right of the $y$ -axis, and how far apart are the intercepts? → $x = \frac{π}{6}$ , every $\frac{π}{3}$

Questions about these worksheets

Yes. Every asymptotes and intercepts of trig functions sheet is free to print and free to download as a PDF. There is no account to make, no email to hand over and no limit on how many you take.

Yes. The answer key prints on a second page, and you can choose whether it shows each question beside its answer or just the answers in a list.

Yes. Print straight from the page, or download the PDF and print that. The sheet is laid out for paper rather than squeezed off a screen, so there is room to work under each question, and the answer key comes out on its own page.

Algebra 2 is usually taken around 10th or 11th grade, though schools vary and plenty of students meet it earlier or later. Pick the difficulty rather than the grade: the easy level suits a first lesson on it, the hard level suits review before a test.

Yes, as many as you like. The questions are built fresh each time rather than picked from a fixed set of files, so pressing Generate gives a new sheet. That is what you want for a second class, a retake, or two students sitting next to each other.

That is the closest comparison, and Kuta Software is good software. It is also paid software you install on a computer. These worksheets run in a browser tab for free, with no account and nothing to install. Like Kuta, the asymptotes and intercepts of trig functions questions are generated when you ask for them rather than pulled from a fixed set of files, so two classes never get the same sheet, and the answer key comes with it.

Yes. There are three levels, and you can tick more than one for a sheet that mixes them, in which case the questions come out easiest first. The harder levels are not just larger numbers: they ask for something the easy ones do not.

You pick from 2: where the asymptotes are and where the x-intercepts are. Tick as many as you want and set how many of each, or let it spread them evenly.

Forgetting to divide by b. The asymptotes of tan(3x) are three times as close together as those of tan x.
