limit as x approaches 0 of (sin(3x))/(tan(10x))

x \to 0 lim (\frac{sin ( 3 x )}{tan ( 10 x )})

\frac{3}{10}

Decimal

0.3

Solution steps

x \to 0 lim (\frac{sin ( 3 x )}{tan ( 10 x )})

Apply L'Hopital's Rule

: x \to 0 lim (\frac{cos ( 3 x ) \cdot 3}{sec ^{2} ( 10 x ) \cdot 10})

= x \to 0 lim (\frac{cos ( 3 x ) \cdot 3}{sec ^{2} ( 10 x ) \cdot 10})

Plug in the value

x = 0

= \frac{cos ( 3 \cdot 0 ) \cdot 3}{sec ^{2} ( 10 \cdot 0 ) \cdot 10}

Simplify

\frac{cos ( 3 \cdot 0 ) \cdot 3}{sec ^{2} ( 10 \cdot 0 ) \cdot 10} : \frac{3}{10}

= \frac{3}{10}

y^{^{''}} + 6 y^{^{'}} + 18 y = 0, y (\frac{π}{2}) = 0, y^{^{'}} (\frac{π}{2}) = 6

\frac{d}{d x} (5 x^{2} (x - 5)^{4})

\frac{d ^{2}}{d x ^{2}} (x^{\frac{1}{10}})

y = 2 x + 1, (1, 5)

\int cos (5 x) x d x
