1 + cos (15 0^{\circ})

Use the following trivial identity:

cos (15 0^{\circ}) = - \frac{3}{2}

= 1 - \frac{3}{2}

Popular Examples

sqrt((280)^2+(190)^2-2(280)(190)cos(80))

(280)^{2} + (190)^{2} - 2 (280) (190) cos (8 0^{\circ})

(20tan(120))/(24cot(150))

\frac{20 tan ( 12 0 ^{\circ} )}{24 cot ( 15 0 ^{\circ} )}

sin(pi/4)-4cos(pi/3)

sin (\frac{π}{4}) - 4 cos (\frac{π}{3})

tan (- 66 0^{\circ})

30 \cdot csc (4 5^{\circ})
