In what situation would you use the sine or cosine law, rather than just a simple trigonometric ratio?

Answer :

Answer:

Mechanical work or work, kinetic and potential energy, etc

Step-by-step explanation:

Like in this work equation, W= FcosD

where F is the magnitude of the force acting on the object

where D is the magnitude of the object's displacement

where cos is the angle between the force and displacement vectors

hope that helps..
