15*tan(27)

15 \cdot tan (2 7^{\circ})

15 10 5 - 5 - 32 5 - 5 + 11 - 45

Solution steps

15 tan (2 7^{\circ})

Rewrite using trig identities:

tan (2 7^{\circ}) = 10 5 - 5 - 32 5 - 5 + 11 - 45

= 15 10 5 - 5 - 32 5 - 5 + 11 - 45

arctan (- 0.4)

2 sin (\frac{5 π}{4}) + 2 cos (\frac{5 π}{4})

\frac{2 tan ( 7 5 ^{\circ} )}{1 - tan ^{2} ( 7 5 ^{\circ} )}

3 tan (6 0^{\circ}) cot (3 0^{\circ}) sin (4 5^{\circ}) csc (4 5^{\circ})

\frac{sin ( 3 7 ^{\circ} ) + 3}{2 sin ( 3 7 ^{\circ} )}
