For the given trigonometric identity, (a) verify the identity and (b) determine whether the identity is true for the given value of x. Explain. \frac{\sec x}{\tan x} = \frac{\tan x}{\sec x - \cos x}, x = \pi Verify the identity: tan\left(\dfrac{\pi...
sin(x)cos(x)cos(x) Cancel theofcos(x). sin(x) sin(x)sin(x) Because the two sides have been shown to beequivalent, theequationis anidentity. tan(x)sec(x)=sin(x)tan(x)sec(x)=sin(x)is anidentity tan(x)sec(x)=sin(x)tan(x)sec(x)=sin(x) ...
sin 2x = (2tan x)/(1 + tan2x) (in terms of tan) These are the main formulas of sin 2x. But we can write this formula in terms of sin x (or) cos x alone using thetrigonometric identitysin2x + cos2x = 1. Using this trigonometric identity, we can write sinx = √(1 - ...
