When working with right triangles, keep in mind that the same rules apply regardless of the orientation of the triangle. In fact, we can evaluate the six trigonometric functions of either of the two acute angles in the triangle in
[link] . The side opposite one acute angle is the side adjacent to the other acute angle, and vice versa.
Many problems ask for all six trigonometric functions for a given angle in a triangle. A possible strategy to use is to find the sine, cosine, and tangent of the angles first. Then, find the other trigonometric functions easily using the reciprocals.
Given the side lengths of a right triangle, evaluate the six trigonometric functions of one of the acute angles.
If needed, draw the right triangle and label the angle provided.
Identify the angle, the adjacent side, the side opposite the angle, and the hypotenuse of the right triangle.
Find the required function:
sine as the ratio of the opposite side to the hypotenuse
cosine as the ratio of the adjacent side to the hypotenuse
tangent as the ratio of the opposite side to the adjacent side
secant as the ratio of the hypotenuse to the adjacent side
cosecant as the ratio of the hypotenuse to the opposite side
cotangent as the ratio of the adjacent side to the opposite side

Finding trigonometric functions of special angles using side lengths
It is helpful to evaluate the trigonometric functions as they relate to the special angles—multiples of
and
Remember, however, that when dealing with right triangles, we are limited to angles between
Suppose we have a
triangle, which can also be described as a
triangle. The sides have lengths in the relation
The sides of a
triangle, which can also be described as a
triangle, have lengths in the relation
These relations are shown in
[link] .
We can then use the ratios of the side lengths to evaluate trigonometric functions of special angles.
Given trigonometric functions of a special angle, evaluate using side lengths.
Use the side lengths shown in
[link] for the special angle you wish to evaluate.
Use the ratio of side lengths appropriate to the function you wish to evaluate.

In economics, a perfect market refers to a theoretical construct where all participants have perfect information, goods are homogenous, there are no barriers to entry or exit, and prices are determined solely by supply and demand. It's an idealized model used for analysis,

Quantity demanded refers to the specific amount of a good or service that consumers are willing and able to purchase at a give price and within a specific time period. Demand, on the other hand, is a broader concept that encompasses the entire relationship between price and quantity demanded

What do you think is more important to focus on when considering inequality ?
sir...I just want to ask one question... Define the term contract curve? if you are free please help me to find this answer 🙏
Asui
it is a curve that we get after connecting the pareto optimal combinations of two consumers after their mutually beneficial trade offs

thank you so much 👍 sir

In economics, the contract curve refers to the set of points in an Edgeworth box diagram where both parties involved in a trade cannot be made better off without making one of them worse off. It represents the Pareto efficient allocations of goods between two individuals or entities, where neither p
