Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y = ← k is the constant of variation
To find k use the condition that x = 9 when y = 15
15 = ( multiply both sides by 9 )
k = 135
y = ← equation of variation
Given a complex number in the form:
The nth-power of this number,
, can be calculated as follows:
- the modulus of
is equal to the nth-power of the modulus of z, while the angle of
is equal to n multiplied the angle of z, so:
In our case, n=3, so
is equal to
(1)
And since
and both sine and cosine are periodic in
, (1) becomes
