((3pi)/2)cos(0)-sec(2pi)

(\frac{3 π}{2}) cos (0) - sec (2 π)

\frac{3 π}{2} - 1

Solution steps

(\frac{3 π}{2}) cos (0) - sec (2 π)

= \frac{3 π}{2} cos (0) - sec (2 π)

Use the following trivial identity:

cos (0) = 1

Rewrite using trig identities:

sec (2 π) = 1

= \frac{3 π}{2} \cdot 1 - 1

Simplify

= \frac{3 π}{2} - 1

sin^{3} (\frac{3 π}{4})

csc (- 1 4^{\circ})

- 1 sin (3 0^{\circ})

cot (12 9^{\circ})

18 sin (4 5^{\circ})
