Verifying Trigonometric Identities Botes 5.2 Choose the least complicated side of the equation, then make the other side match using your algebraic knowledge and trig identities. Verify or prove each identity. Ex 1: cosxsec xtanx - cosxtan'x = sinx Ex 2: (sec2 x - 1) (sin2 x - 1) = -sin2 x Sin 'x Eco-six ) =- sink - Sin 2x ...
