👉 Learn how to evaluate the six trigonometric functions given some constraints. When given the value of one trigonometric ...

In this video series, we explore the definitions of trigonometric identities. It is very important when simplifying, verifying, and solving trigonometric problems that we know the trig identities. We ...

Solve the equation \(4\sin x^\circ - 3 = 0\), where \(0 \le x \textless 360\). From the graph of the function, we can see that we should be expecting 2 solutions: 1 solution between \(0^\circ\) and ...

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 ...

Trigonometry is the branch of mathematics that explains the relationship between sides and angles of a triangle. In a right angled triangle the three sides are perpendicular, base and hypotenuse, as ...
