Popular Examples

cos(330)*sin(-210)-tan(-315)*cot(-330)

cos (33 0^{\circ}) \cdot sin (- 21 0^{\circ}) - tan (- 31 5^{\circ}) \cdot cot (- 33 0^{\circ})

(200)/(sin(25))

\frac{200}{sin ( 2 5 ^{\circ} )}

tan (\frac{1}{2} + \frac{1}{3})

sqrt((100^2+120^2-2*100*120*cos(60)))

(10 0^{2} + 12 0^{2} - 2 \cdot 100 \cdot 120 \cdot cos (6 0^{\circ}))

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