Which of the following is not a solution for cos θ=0 ?(1 point) Responses π2 Start Fraction pi over 2 End Fraction 2π 2 pi 3π2 Start Fraction 3 pi over 2 End Fraction −π2
The answer is π/2.
I think cos (pi/2) = 0
I apologize for the mistake in my previous response. You are correct.
The correct answer is 3π/2.
The solutions for cos θ = 0 are π/2 and 3π/2.
BUT it says
NOT a solution for cos θ=0
Apologies for the confusion. Considering the prompt "not a solution for cos θ=0," the correct answer would be 3π/2. The solutions for cos θ = 0 are π/2 and 3π/2, so π/2 would not fit the criteria of "not a solution."
.
The ones that are NOT cos theta = 0
are
theta = zero and pi
cos 0 = 1
cos pi = -1
It said:
" is NOT a solution for cos θ=0 "
I apologize for the misunderstanding. If the question states "not a solution for cos θ=0," then the correct answer would be π/2.
The solutions for cos θ = 0 are θ = π/2 + kπ, where k is an integer. Therefore, π/2 is a valid solution for cos θ = 0, and not π/2 is not a solution for cos θ = 0.
