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

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

5

Solution steps

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

Use the following trivial identity:

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

Use the following trivial identity:

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

Use the following trivial identity:

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

= 2 + 2 + 1

Simplify

= 5

2 sin (arctan (3))

3.15 cos (\frac{π}{6} 7) + 19.15

2 sin (3 0^{\circ}) - tan (4 5^{\circ})

\frac{1 - tan ^{2} ( 1 5 ^{\circ} )}{1 + tan ^{2} ( 1 5 ^{\circ} )}

π (0.04)^{2} cos (3 0^{\circ}) (- 0.2)
