sin$\theta$sec$\theta$ = tan$\theta$ $\frac{sin\theta}{}\frac{1}{cos\theta}$ = $tan\theta$ $\frac{sin\theta}{cos\theta} = tan\theta$ $tan\theta = tan\theta$

Work Step by Step

Note: sec(x) = $\frac{1}{cos(x)}$ sin$\theta$sec$\theta$ = tan$\theta$ Using the note above: $\frac{sin\theta}{}\frac{1}{cos\theta}$ = $tan\theta$ $\frac{sin\theta}{cos\theta} = tan\theta$ $tan\theta = tan\theta$
