Verify the Identity:
\(\displaystyle \frac{\sec{\theta}-1}{1-\cos{\theta}} = \sec\theta\)
i did... \(\displaystyle \frac{\sec{\theta}-1}{1-\cos{\theta}}*\frac{1+\cos{\theta}}{1+\cos{\theta}}\)
\(\displaystyle \frac{(\sec\theta-1)(1+\cos\theta)}{1-\cos^2\theta}\)
\(\displaystyle \frac{\sec\theta+\sec\theta\cos\theta-1-\cos\theta}{\sin^2\theta}\)
and now im stuck i think i did the first steps right...can any one help please?
