Today we're talking about sine and cosine, or rather sine cosine tangent! Obviously always here on this fantastic channel the physics we like!  In fact, in this lesson I will explain to you in a simple and clear way how to define the sine, cosine and tangent of an angle. We will start first from the trigonometric circle, that is, a circumference with center in the origin and radius one. After that we could define the sine as the ordinate of a certain point P on the circumference, the cosine as the abscissa of this point P, while the tangent will be a little more complicated to define but you will see it just as clearly! I will also give you the explanation of a couple of formulas that you know very well, but without further ado and let's move on to the live!  For some time I have been offering additional supplementary lessons and completed exercises that best complement everything I do here on YouTube. Don't waste your time! You have two different options: subscribe to my YouTube channel or subscribe now to one of my TIERS (the number of subscriptions is limited) You know that in my channel there are physics videos: studying physics is often not easy, I know, but with me you will study physics in a simple and fun way, increasing your knowledge and improving your grades both in class tests and in oral tests! Don't forget to take a look at my playlists looking for the physics 1 or physics 2 topics that interest you! I have also inserted 2 special playlists: one dedicated to the advice I want to give you to improve your studies and face the school year at the top and another dedicated to the largest particle physics laboratory in the world!
