Differentiate the function. f(x) = ln(25 sin^2(x))

tigry1 [53]

Use the chain rule.
Let u = 25sin²(x), such that dy/dx = dy/du · du/dx

$\frac{dy}{dx} = \frac{1}{25sin^{2}(x)} \cdot 50cos(x) \cdot sin(x)$
$\frac{dy}{dx} = \frac{2cos(x) sin(x)}{sin^{2}(x)}$

$\frac{dy}{dx} = 2cot(x)$

<PTQ=90

In ∆PTQ

Apply Pythagorean theorem

$\\ \tt\hookrightarrow PT^2=PQ^2+QT^2$

$\\ \tt\hookrightarrow PT^2=15.4^2+9.3^2=323.16$

$\\ \tt\hookrightarrow PT=17.9$

In ∆TRQ

$\\ \tt\hookrightarrow tan44.4=\dfrac{QT}{TR}=\dfrac{9.3}{TR}$

$\\ \tt\hookrightarrow 0.9=\dfrac{9.3}{TR}$

$\\ \tt\hookrightarrow TR=\dfrac{9.3}{0.9}=10.3$

PR=PT+TR=10.3+17.9=28.2cm

Now

Area:-

$\\ \tt\hookrightarrow 1/2bh$

$\\ \tt\hookrightarrow 1/2(28.2)(9.3)$

$\\ \tt\hookrightarrow 14.1(9.3)$

$\\ \tt\hookrightarrow 131.13cm^2$
