Underneath the … WebTrigonometric Identity : Given : sin 2 x tan 2 x = tan 2 x - sin 2 x. Step 1.) we know that tanx is equal to sinx/cosx so we can use this to find the tan 2 x. tanx = cosxsinx. tan2x = cos2xsin2x. Step 2.) we will manipulate the left side of the equation. sin2xtan2x = tan2x−sin2x. sin2xcos2xsin2x = tan2x−sin2x. cos2x(sin2x)(sin2x) = tan2x− ...
