Answer:
the right side
Step-by-step explanation:
If you have some knowledge of complex numbers: This follows pretty much immediately from Euler's formula and DeMoivre's theorem,
(Euler)
(DeMoivre)
so that is the imaginary part of the expanded left hand side.
If that's unfamiliar to you, you can make use of several identities to expand :
(double angle sine)
(double angle sine and cosine)
(Pythagorean)
First, you need to multiply 3x5 and Sunday you 2B-3B. Now the problem is 18-15+-1. Since there is no exponents, multiplication, or division in this problem anymore, we are going to add. 15+-1=0. Now we have 18-0. 18-0=18. Therefore the answer is 18
The correct option is A, which is {(5/7, 12/7)}.
<h2>Given to us,</h2>
equation 1, 5x + 2y = 7,
equation 2, y = x+1
To solve the question, as given in equation 2 the value of y which is equal to x+1, Substitute the value of y in equation 1,
<h3>substituting,</h3>
Now, we have the value of x, substitute the value in equation 2, to get y,
Taking LCM,
Hence, the correct option is A, which is {(5/7, 12/7)}.
