Answer:

θ = πk, 1.318+2πk, 4.965+2πk

Step-by-step explanation:

4sin(2θ) − 2sin(θ) = 0

8sin(θ)cos(θ) - 2sin(θ) = 0

2sin(θ)[4cos(θ)-1] = 0

2sin(θ) = 0

sin(θ) = 0

θ = πk

4cos(θ)-1 = 0

4cos(θ) = 1

cos(θ) = 1/4

θ ≈ 1.318+2πk, 4.965+2πk

Therefore, θ = πk, 1.318+2πk, 4.965+2πk

          Which expression has least value when x=100?

\diamond\large\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}\diamond

Substitute 100 for x and solve:-

\bold{\dfrac{1}{100}}

\bold{\dfrac{10}{100}}

\bold{1-100=-99}

\bold{10-100=-90}

Since -99 is the smallest number here, the expression with the least value when x=100 is Option C - \checkmark\dashrightarrow\boxed{\boxed{1-x}}}\dashleftarrow\checkmark

<h3>Good luck.</h3>
