Quadrantal angles (0, 90, 180, and 270 degrees), and the values of the sine, cosine, and tangent of each of these angles. From the trig lessons in the Algebra 2 course by Derek Owens.
From one of the vertices drop a perpendicular to the opposite side dividing that side in two lengths each of length 1 unit. The perpendicular is of length sqrt{2^2 - 1^2} = sqrt{4-1} = sqrt{3} The perpendicular bisector divides the 60 degree angle into two equal angles each of 30 degrees.We now have a triangle of 30, 60, 90 degrees with corresponding opposite sides of 1 unit, sqrt{3} units, 2 units respectively.he hypotenuse will in such a case be sqrt{1^2 + 1^2} = sqrt{1+1} = sqrt{2}. Sine(45) = Opposite Side/Hypotenuse = 1/[sqrt(2)] Cosine(45) = Adjacent Side/Hypotenuse = 1/[sqrt(2)] Tangent(45) = Opposite Side/Hypotenuse = 1/1 = 1 As regards the 30 and 60 degrees: Consider an equilateral triangle of side 2 unit each side.
