sin (4 \cdot \frac{π}{4})

Solution

0

Solution steps

sin (4 \cdot \frac{π}{4})

Simplify:

4 \cdot \frac{π}{4} = π

= sin (π)

Use the following trivial identity:

sin (π) = 0

= 0

Popular Examples

(sin(30))/(sin(22.5))

\frac{sin ( 3 0 ^{\circ} )}{sin ( 22. 5 ^{\circ} )}

(cos(pi/6))/(-sin(pi/6))

\frac{cos ( \frac{π}{6} )}{- sin ( \frac{π}{6} )}

cos^2((3pi)/8)+cos^2(pi/8)

cos^{2} (\frac{3 π}{8}) + cos^{2} (\frac{π}{8})

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

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

tan^{2} (1921 4^{\circ})
