Review the proof of de Moivre's theorem. What is the justification for step B?
Proof of de Moivre's Theorem
O distributive property
O factoring
O multiplication rule
O assumption (for n= k step)
[cos(O) + i sin(e)]+1
A = (cos(0) + i sin(O)]* . [cos(O) + i sin(O)]
B = [cos(ko) + i sin(ke)] . [cos(0) + i sin(O)]
C = cos(KO)cos(0) - sin(ko)sin(0) +i (sin(ko) cos(0) +
cos(ko) sin(0)]
D = cos(kO + ) + i sin(ke + 0)
E = cos[(k + 1)] + i sin[(k + 1)]

answer: what if i dont want to show my work boi.

step-by-step explanation: im watching dbz and eating popcorn leave meh alone

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

the 3rd on is correct
