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})

Use the following property:

sin (- x) = - sin (x)

sin (- \frac{3 π}{2}) = - sin (\frac{3 π}{2})

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

Use the following property:

cos (- x) = cos (x)

cos (- \frac{3 π}{2}) = cos (\frac{3 π}{2})

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

Simplify

= 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
