Trigonometrical ratios

Worksheet overview

Descripción:

As Thales' theorem tells us, trigonometrical ratios of an angle do not depend on the right-angled triangle we choose. Therefore, we can choose a right-angled triangle whose hypotenuse is the radius of a unit circle. We have drawn a set of axes and used the origin as the centre of an auxiliary circle whose radius is equal to one unit. We have drawn a right-angled triangle in the circle, which we will use to define the trigonometrical ratios. By choosing a radius of this length we have made it easier to find, for each trigonometrical ratio of a given angle, a segment whose length is equal to this ratio. This circle whose radius is equal to one unit is called the unit circle.

Orientación didáctica:

KNOWLEDGE TYPE: procedural

LEARNING OBJECTIVES * To learn the trigonometrical ratios of angles. * To find the relation between the different trigonometrical ratios of the same angle. * To find the relation between the trigonometrical ratios of complementary and supplementary angles, as well as angles with a difference of p radians and opposite angles. * Recognise the relation that exists between the sides of a right-angled triangle.
