simplify tan(2x-pi/2)-1

simplify

tan (2 x - \frac{π}{2}) - 1

- cot (2 x) - 1

Solution steps

tan (2 x - \frac{π}{2}) - 1

Rewrite using trig identities

= - \frac{cos ( 2 x )}{sin ( 2 x )} - 1

Use the basic trigonometric identity:

\frac{cos ( x )}{sin ( x )} = cot (x)

= - cot (2 x) - 1

cot (arcsec (\frac{x}{a}))

cos ((t - π) + π)

cos (x - \frac{π}{5})

tan (t + π)

cos (- 5 t)
