What is the lim (1-cos theta)/(2sin^2 theta) as theta approahes 0?

Sergio039 [100]

$\displaystyle
\lim_{\theta\to 0}\dfrac{1-\cos \theta}{2\sin ^2\theta}=\\\\
\lim_{\theta\to 0}\dfrac{(1-\cos \theta)(1+\cos \theta)}{2\sin ^2\theta(1+\cos \theta)}=\\\\
\lim_{\theta\to 0}\dfrac{1-\cos^2 \theta}{2\sin ^2\theta+2\sin^2 \theta\cos \theta}=\\\\
\lim_{\theta\to 0}\dfrac{\sin^2 \theta}{2\sin ^2\theta+2\sin^2 \theta\cos \theta}=\\\\
\lim_{\theta\to 0}\dfrac{1}{2+2\cos \theta}=\\\\
\dfrac{1}{2+2\cdot1}=\\\\
\dfrac{1}{4}

Asanji left the science museum and drove toward the lake at an average speed of 45 km/h. Sometime later Huong left driving in th

Cloud [144]

Answer:

Asanji drove for $5$ hours before Huong caught up

Step-by-step explanation:

Let the time for which Asanji drove alone is "X" hours

Asanji and Huong met after three hours of driving of Huong.

Total time for which Asanji drove $= X+3$ hours

Thus, distance travelled by Asanji in $X+3$ hours is equal to distance travelled by Huong in $3$ hours

$45 ( X+3) = 75 (3)\\$

On solving the above equation, we get -

$45 X + (45 *3) = 75 *3\\45 X = (75-45)*3\\45 X = 30 *3 \\X = \frac{30 *3}{45} \\X = 2$

Asanji drove for $3 + 2 = 5$ hours before Huong caught up
