cos((3pi)/2)+isin((3pi)/2)

cos (\frac{3 π}{2}) + i sin (\frac{3 π}{2})

Undefined

Solution steps

cos (\frac{3 π}{2}) + i sin (\frac{3 π}{2})

Rewrite using trig identities:

cos (\frac{3 π}{2}) = \frac{1}{sec ( \frac{3 π}{2} )}

= \frac{1}{sec ( \frac{3 π}{2} )} + i sin (\frac{3 π}{2})

Rewrite using trig identities:

sec (\frac{3 π}{2}) =

Undefined

= Undefined
