these all are the trigonometric ratios of side of triangle
Sidhesh:
these are just ratio
Concentrate on ur book rather than on brainly u will be fully satisfied
i just want to be prepare for this topic
everyone in my class says that this is hard
Yep but interesting

In mathematics, the sine is a trigonometric function of anangle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse).
In a right angled triangle, the cosine of an angle is: The length of the adjacent side divided by the length of the hypotenuse. The abbreviation is cos. cos θ = adjacent / hypotenuse.
Tangent are the main functions used in Trigonometry and are based on a Right-Angled Triangle. Before getting stuck into the functions, it helps to give a name to each side of a right triangle: "Opposite" is opposite to the angle θ "Adjacent" is adjacent (next to) to the angle θ
Most often, θ is a variable that stands for an angle in geometry, e.g.: ... Generally, φ represents longitude and θ represents latitude, though the choice is arbitrary. Often, two angles in the same plane are represented by α and β. Theta has many other uses.
