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

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

0

Solution steps

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

Use the following trivial identity:

sin (\frac{3 π}{4}) = \frac{2}{2}

Use the following trivial identity:

sin (\frac{π}{4}) = \frac{2}{2}

= \frac{2}{2} - \frac{2}{2}

Simplify

= 0

sin (\frac{π}{24})

arctan (- \frac{2}{6})

8 \cdot (\frac{2 0 ^{2}}{4 tan ( \frac{0.79}{2} )})

sin (arcsin (\frac{1}{3}) + arctan (\frac{4}{7}))

4 + 3 cos (\frac{π}{4})
