Question

The equation sin( z) = 10 has
(A) no real or complex solution
(B) exactly two distinct complex solutions
(C) a unique solution
(D) an infinite number of complex solutions

Answer 1

(B)exactly two distinct complex solutions

Answer 2

Answer:

The correct answer will be (A) no real or complex solution

Step-by-step explanation:

Given sin(z) = 10

But the sin function has a maximum limit of +1 and minimum limit of -1.

i.e. -1 ≤ sin z ≤ +1

Hence sin function greater than +1 can not exist.

So sin z = 10 is not possible.

Hence there will be no real or complex solution for the above equation.

So option (A) no real or complex solution will be the correct answer.
