Webtan^2 = sin^2+cos^2 = 1 << this we can agree on the solutions tell us to divide both sides by cos^2. so sin^2/cos^2 + cos^2/cos^2 = 1/cos^2 and 1/cos^2 is sec^2 << still following then somehow it says therefore tan^2-1 = sec^2 so it replaces the entire first argument with sec^2, completely ignoring that 1 we were supposed to deduct from tan.
