$\frac{1-\sec\left(x\right)^2}{\sec\left(x\right)^2}$
Learn how to solve proving trigonometric identities problems step by step online. Prove the trigonometric identity (1-sec(x)^2)/(sec(x)^2)=-sin(x)^2. Starting from the left-hand side (LHS) of the identity. Apply the trigonometric identity: -\sec\left(\theta \right)^2+1=-\tan\left(\theta \right)^2. Applying the secant identity: \displaystyle\sec\left(\theta\right)=\frac{1}{\cos\left(\theta\right)}. Divide fractions \frac{-\tan\left(x\right)^2}{\frac{1}{\cos\left(x\right)^2}} with Keep, Change, Flip: a\div \frac{b}{c}=\frac{a}{1}\div\frac{b}{c}=\frac{a}{1}\times\frac{c}{b}=\frac{a\cdot c}{b}.
