Calculate the angle QPR. Give the answer to one decimal place. Label the sides of the triangle \(o\), \(a\) and \(h\). Next choose the correct ratio from \(s^o_h~c^a_h~t^o_a\). In the triangle the ...

The angles are labelled with capital letters. The opposite sides are labelled with lower case letters. Notice that an angle and its opposite side are the same letter. The sine rule is: \(\frac{a} ...

For example, 30° clockwise from north is usually written as 030°. Problems involving bearings can be worked out as you would work out problems with triangles using the sine or cosine rule: ...

The trigonometric ratios sine, cosine and tangent are used to calculate angles and sides in right angled triangles. We are now going to extend trigonometry beyond right angled triangles and use it ...

The mileage covered by trucks with four or more axles, which are subject to toll charges, on German motorways increased by 1.4% in October 2024 compared with September 2024, after calendar and ...

In a function such as sine or cosine, we could also have a translation of the form: \(y = \sin (x - a)^\circ\) where \(a\) is called the phase angle. This is when the graph of the function has ...
