cos(pi/4)+isin(pi/4)

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

\frac{2}{2} + i \frac{2}{2}

Solution steps

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

Use the following trivial identity:

cos (\frac{π}{4}) = \frac{2}{2}

Use the following trivial identity:

sin (\frac{π}{4}) = \frac{2}{2}

= \frac{2}{2} + i \frac{2}{2}

arcsin (sin (\frac{4 π}{7}))

cos (π) + sin (π)

- cos (3 π)

10 cos (4 0^{\circ})

arcsin (\frac{2}{2})

What is the value of cos(pi/4)+isin(pi/4) ?
The value of cos(pi/4)+isin(pi/4) is (sqrt(2))/2+i(sqrt(2))/2
