WebNote that the three identities above all involve squaring and the number 1.You can see the Pythagorean-Thereom relationship clearly if you consider the unit circle, where the angle is t, the "opposite" side is sin(t) = y, the "adjacent" side is cos(t) = x, and the hypotenuse is 1.. We have additional identities related to the functional status of the trig ratios: WebSep 7, 2014 · Sep 7, 2014. d dx sec(x) = sec(x)tan(x) You could memorize this, but you can work it out too by knowing some trig properties. The trig properties we will use are: sec(x) = 1 cos(x) and sinx cosx = tanx. Deriving: d dx sec(x) = d dx 1 cos(x) = cos(x)(0) −1( −sin(x)) cos(x)cos(x) (using the quotient rule) = sin(x) cos(x)cos(x) = sin(x) cos(x ...
