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

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

\frac{2 3}{3} + 2

Decimal Notation

2.56891 \dots

Solution steps

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

Use the following trivial identity:

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

tan (4 5^{\circ})

tan (x)

periodicity table with

18 0^{\circ} n

cycle:

x 0 3 0^{\circ} 4 5^{\circ} 6 0^{\circ} 9 0^{\circ} 12 0^{\circ} 13 5^{\circ} 15 0^{\circ} tan (x) 0 \frac{3}{3} 13 \pm \infty - 3 - 1 - \frac{3}{3}

= 1

Use the following trivial identity:

sec (3 0^{\circ}) = \frac{2 3}{3}

sec (3 0^{\circ})

sec (x)

periodicity table with

36 0^{\circ} n

cycle:

= \frac{2 3}{3}

Use the following trivial identity:

csc (4 5^{\circ}) = 2

csc (4 5^{\circ})

csc (x)

periodicity table with

36 0^{\circ} n

= 2

= 1 \cdot \frac{2 3}{3} + 2

Simplify

= \frac{2 3}{3} + 2

1 - 2 sin^{2} (\frac{2 π}{5})

12 \cdot sin (5 1^{\circ}) \cdot 2.08 - \frac{9.81}{2} \cdot 2.0 8^{2}

sin (4 \cdot \frac{π}{6})

\frac{3 cos ( 0.5 ( 21 ) )}{e ^{(- 0.1 (21))}}

\frac{3}{tan ( 22. 5 ^{\circ} )}
