sin((2pi)/2)+cos((2pi)/2)

sin (\frac{2 π}{2}) + cos (\frac{2 π}{2})

- 1

Solution steps

sin (\frac{2 π}{2}) + cos (\frac{2 π}{2})

Simplify

= sin (π) + cos (π)

Use the following trivial identity:

sin (π) = 0

Use the following trivial identity:

cos (π) = (- 1)

= 0 - 1

Simplify

= - 1

cos (5.5)

- 51.875 cos (\frac{2 π}{365} (55 - 354)) + 727.725

(cot (1 0^{\circ}) - cot (8 0^{\circ})) tan (2 0^{\circ})

cos (\frac{17 π}{6}) \cdot sec (- 6 0^{\circ}) + cot (21 0^{\circ})

sec (\frac{19 π}{3})
