Yes, I have searched on google/youtube but I want to know how to work with them in tasks for example ramp friction
##f=mgcos0##
##f=mgcos0##
-Physician said:Just 1 more question, what to do if we have ##cos30## for e.x
Cosine (cos) and sine (sin) are two fundamental trigonometric functions used in mathematics and science. They represent the ratio of sides of a right triangle in relation to one of its angles.
Cosine and sine are used in a variety of real-world applications, including navigation, engineering, physics, and astronomy. They are used to calculate distances, angles, and forces in various systems and structures.
To work with cosine and sine, you will need to understand their properties and how they relate to each other. You will also need to know how to use trigonometric identities and formulas to solve equations and problems involving cosine and sine.
Yes, some common mistakes when working with cosine and sine include forgetting to convert between degrees and radians, using the wrong trigonometric identity or formula, or incorrectly setting up the problem or equation.
To master cosine and sine, it is important to practice regularly, understand the concepts and properties, and familiarize yourself with common identities and formulas. It can also be helpful to visualize and draw out problems to better understand the relationships between angles and sides.
