Look at the icon below:
Notice the triangle icon above, the KLM triangle is an equilateral triangle. We decide trigonometric ratio values for every 30° in addition to 60°.
Furthermore our focus is the MPL triangle. With the phytagoras theorem, obtained the length of MP = √3. It is thence applicable:
- sin 30° = 1/2
- cos 30° = √3/2
- tan 30° = √3/3
- sin 60° = √3/2
- cos 60° = 1/2
- tan 60° = √3
For to a greater extent than information, the value of whatsoever trigonometric ratio at whatsoever especial angle of 0 °, thirty °, 45 °, lx °, ninety °, upwards to 360 ° tin live on seen inwards the tabular array below:
