Final answer:
Trigonometry is a branch of mathematics that deals with the relationship between angles and sides of right-angled triangles. Regular trigonometric functions such as sine, cosine, and tangent are used to find the values of missing sides or angles in a right triangle. Inverse trigonometric functions are used to find the value of the missing angle in a right triangle.
Step-by-step explanation:
Trigonometry is a branch of mathematics that deals with the relationship between angles and sides of right-angled triangles. Regular trigonometric functions such as sine, cosine, and tangent are used to find the values of missing sides or angles in a right triangle. Inverse trigonometric functions, on the other hand, are used to find the value of the missing angle in a right triangle.
For example, if we have a right triangle with known values of two sides (adjacent and opposite), we can use the trigonometric functions cosine and sine to find the missing angle. Similarly, if we know the values of one side and the angle, we can use inverse trigonometric functions to find the length of the missing side.
Trigonometry is a fundamental concept in mathematics and can be applied in various fields such as physics, engineering, and navigation.
