csc(30)+cot(45)+sec(60)

csc (3 0^{\circ}) + cot (4 5^{\circ}) + sec (6 0^{\circ})

5

Solution steps

csc (3 0^{\circ}) + cot (4 5^{\circ}) + sec (6 0^{\circ})

Use the following trivial identity:

csc (3 0^{\circ}) = 2

Use the following trivial identity:

cot (4 5^{\circ}) = 1

Use the following trivial identity:

sec (6 0^{\circ}) = 2

= 2 + 1 + 2

Simplify

= 5

arctan (\frac{33}{40})

arccos (- \frac{1}{2} 2)

sin (6 0^{\circ}) \cdot 5

30 sin (9 0^{\circ})

arctan (1.82)
