answer:To prove the identity, we will start with the left-hand side (LHS) and simplify it to obtain the right-hand side (RHS): begin{align} text{LHS} &= frac{1}{cos(alpha)}-tan(alpha) [0.3cm] &= frac{1}{cos(alpha)}-frac{sin(alpha)}{cos(alpha)} [0.3cm] &= frac{1-sin(alpha)}{cos(alpha)} [0.3cm] &= frac{cos^2(alpha)}{cos(alpha)} qquad [text{Using } cos^2(alpha) = 1 - sin^2(alpha)][0.3cm] &= cos(alpha) [0.3cm] &= sec(alpha) [0.3cm] &= text{RHS} end{align} Therefore, the given trigonometric identity is proved.
