The following Topics and Sub-Topics are covered in this chapter and are available on MSVgo:
Basic trigonometry deals with three fundamental ratios, namely the sine, cosine and tan ratios. These ratios correspond to the ratios of the different sides of a right-angled triangle. The whole trigonometry ratios are based on the right triangle. The basic trigonometric functions for the right-angled triangle are given below.
In the above triangle, angle B is a right angle. Hence, now we can calculate different trigonometric ratios for the above triangle.
Some of the applications of trigonometry are given below.
While solving various algebraic expressions, you can easily use trigonometric identities to get to the answer quickly. As we said before, you can use trigonometric ratios for solving even traditional geometrical problems. Sine, cosine, and tangent are the three basic trigonometric identities. The rest of the identities are based on these. Hence, explore these three basic identities, and you can follow up with the rest.
Trigonometric ratios of complementary angles include the identity of two angles whose sum is 90 degrees. Therefore, if we have an angle A, then its complementary angle will be 90-A.
Trigonometry is considered an ancient mathematical tool developed during the Greek period of Hipparchus. We know that there are many great Greek mathematicians and philosophers that gave us some of the best mathematical concepts that still find their use. There are six main trigonometric functions that are used throughout the trigonometric concepts. These trigonometric functions are used in various applications such as navigation, mapping, engineering and more.
