Since $x$- and $y$-coordinates can be positive, negative, or zero, the graphs of tangent and cotangent functions pose some interesting behavior; in particular, when ...

Trigonometry is the branch of math that studies triangles, with a particular focus on the relationships between angles and the lengths of corresponding sides. Interestingly enough, the trigonometric ...

We can graph the sine and cosine functions in the same manner we can graph any function: by plotting points and then connecting them. \newline\\ \pause If we let the ...

Trigonometric graphs can be sketched when you know the amplitude, period, phase and maximum and minimum turning points. Learn about graphs of trigonometric functions in this National 5 Maths guide.

have the same curve only shifted along the x-axis have an amplitude (half the distance between the maximum and minimum values) of 1 have a period (size of one wave) of 360˚ ...

I make short, to-the-point online math tutorials. I struggled with math growing up and have been able to use those experiences to help students improve in math through practical applications and tips.
