Privileges of Special Angles in Trigonometry

Privileges of Special Angles in Trigonometry - When studying mathematics, especially the trigonometry chapter, Friend Scientists must be introduced to special angles. Large degrees from these special angles include 30o, 45o, 60o, and 90o. By the way, why is that, the corners are named special angles? Indeed, what is so special about this angle when compared to other angles? How do you get that privilege? Then, what is the connection with trigonometry? To be able to answer the question above, see the following explanation, let's say, Friend Scientist !.

Privileges of Special Angles

When asked about the value of sin 23o, what will you do? Calculate the value using formulas or graphs, ask teachers and friends, or calculate using a calculator?

Yes, usually, to find the value of a certain sine, cosine, or tangent, we have no other way than to use a tool in the form of a calculator to find answers quickly. But for some angles, we no longer need to rely on calculating aids.

Why is that? Because these angles, which are more often called special angles, have a relationship with the ratio of the sides of a triangle! How curious about the relationship? Continue reading the discussion below, yes!

Privileges Angles 45o and 90o on Triangles and Trigonometry

Special features of special angles cannot be separated from triangles and trigonometry, buddy of scientists. This is because the special nature indeed fulfills the condition of a certain triangle.

For example, only 45o and 90o special angles. Suppose we form a triangle that has an angle of 45o and 90o. As you know, the total angle of the triangle is 180o. If the triangle already has an angle of 45o and 90o then the last corner it has is 45o so that it forms an equilateral triangle.
