WebTriangles for the trigonometric ratios of special angles. Detailed description of diagram. Interactive 1 . Extending the angles. In the module Further trigonometry (Year 10), we showed how to redefine the trigonometric functions in terms of the coordinates of points on the unit circle. This allows the definition of the trigonometric functions to be extended to … WebWe can read trigonometric definitions right from the triangle as corresponding ratios of sides. Specifically, for angle θ, tan θ = y x, and sec θ = r x. We can now write, 1 + tan 2 θ = 1 + ( y x) 2 = 1 + y 2 x 2 = x 2 + y 2 x 2 = r 2 x 2 = ( r x) 2 = sec 2 θ. Hence Proved.
Web12 Feb 2013 · You want to substitute a function in there, so we choose tan (theta) since it is related to sec (theta) by tan^2 (theta) + 1 = sec^2 (theta). So, in order for this substitution to work out okay, …
