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 ...

The class Trigonometry: Sine, Cosine, and Tangent discusses the three basic ratios that are the basis for trigonometry. Trigonometry is based on the specific relationships between the sides and angles ...

This circle has the centre at the origin and a radius of 1 unit. The point P can move around the circumference of the circle. At point P the \(x\)-coordinate is \(\cos{\theta}\) and the ...

Let’s look at how to use trigonometric identities to calculate missing sides. \({sin~θ} = \frac {opposite} {hypotenuse}\) \({cos~θ} = \frac {adjacent} {hypotenuse ...

Trigonometric identities might seem like abstract mathematical concepts, but they're actually powerful problem-solving tools that can transform seemingly impossible equations into manageable solutions ...
