limit as θ approaches 0 of sin(θ)cot(2θ)

θ \to 0 lim (sin (θ) cot (2 θ))

\frac{1}{2}

Decimal

0.5

Solution steps

θ \to 0 lim (sin (θ) cot (2 θ))

Rewrite for L'Hopital

= θ \to 0 lim (\frac{sin ( θ )}{\frac{1}{c o t ( 2 θ )}})

Apply L'Hopital's Rule

= θ \to 0 lim (\frac{cos ( θ )}{sec ^{2} ( 2 θ ) \cdot 2})

Plug in the value

θ = 0

= \frac{cos ( 0 )}{sec ^{2} ( 2 \cdot 0 ) \cdot 2}

Simplify

\frac{cos ( 0 )}{sec ^{2} ( 2 \cdot 0 ) \cdot 2} : \frac{1}{2}

= \frac{1}{2}
