Let's remind ourselves of what the sine graph looks like so that we can see how many solutions we should be expecting: Therefore, from the graph of the function, we can see that we should be expecting ...

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.

The sine and cosine functions can be used to model fluctuations in temperature data throughout the year. An equation that can be used to model these data is of the ...

In this paper we study a type of trigonometric extremal problem which originates in the work of Arne Beurling in the late 1930s and concerns approximations to the function sgn (x). The extremal ...
