Remember the Sin and Cos table. What is the sin of 30 degrees?

-

    Each angle can be measured in degrees. Do you know what are 90, 189, and 360 degrees?
And can you recognize 30, 45, and 60 degrees?

    In mathematical calculations, usually we do not use degrees. The degrees have to be converted into a number. There are 3 trigonometrical numbers for each angle/ number of degrees - sin, cos, and tan. 

   Let's listen to a song of this Portuguese cat.
