Answer:
B
Step-by-step explanation:
Add 8 to simplify because then you can easily add the xes together
Answer:
where.... are the expressions?
Step-by-step explanation:
<span>cos x = [ e^(ix) - e^(-ix) ] / 2i along with [ A - B ]^5 =
( A^5 - B^5) - 5 AB ( A^3 - B^3) + 10 A²B² (A - B )...A = e^(ix) , B = e^(-ix)
[ cos x ] ^5 = (1/32i) { [ e^(5ix) - e^(-5x) ] - 5 [ ( e^(3ix) - e^(-3ix) ] + 10 [ e^(ix) - e^(-ix) ] }
= ( 1 / 16 ) { cos 5x - 5 cos 3x + 10 cos x }.....much faster</span>
The answer is palleragram sorry i do not know how to spell very well
Answer:
x = 3/4
Step-by-step explanation:
Step 1: Find possibilities.
- We know one possibility: 8x - 6 = 0. This is because 0 cannot be positive or negative.
Step 2: Solve possibility 1.
(Add 6 to both sides)
(Divide both sides by 8)
Therefore, x = 3/4.
