Websin θ + cos θ = √2. Now square on both side. = ( sin θ + cos θ)2 = √22. = (sin2θ + cos2θ) + 2 sin θ cos θ = 2. = 1+ 2sin θ cos θ = 2. ⇒ sin θ cos θ = 1 2 1 2. Now. tanθ + cot θ = sinθ cos θ + cosθ sinθ sin θ cos θ + cos θ sin θ. = sin2 θ+cos2 θ sinθcos θ … Webtan^2x = sin^2x / cos^2x ⇒ tan 2 x = sin 2 x/cos 2 x; tan^2x = 1/cot^2x ⇒ tan 2 x = 1/cot 2 x; What is the Difference Between tan2x and tan^2x? Tan2x is a double angle trigonometric formula which gives the value of the tangent function for the compound angle 2x. On the other hand, tan^2x is the whole square of the trigonometric function tanx.
