sin^2((3pi)/4)

Solution

sin^{2} (\frac{3 π}{4})

Solution

\frac{1}{2}

+1

Solution steps

sin^{2} (\frac{3 π}{4})

Use the following trivial identity:

sin (\frac{3 π}{4}) = \frac{2}{2}

= (\frac{2}{2})^{2}

Simplify

(\frac{2}{2})^{2} : \frac{1}{2}

= \frac{1}{2}

Popular Examples

sin(pi/(12))-sin((17pi)/(12))

sin (\frac{π}{12}) - sin (\frac{17 π}{12})

arccos (\frac{π}{6})

sec (7 π)

2 sin (\frac{5 π}{3})

(sin(150)+sin(120))/(cos(210)-cos(300))

\frac{sin ( 15 0 ^{\circ} ) + sin ( 12 0 ^{\circ} )}{cos ( 21 0 ^{\circ} ) - cos ( 30 0 ^{\circ} )}
