limit as x approaches pi/3 of 7xcos(x)

x \to \frac{π}{3} lim (7 x cos (x))

\frac{7 π}{6}

Decimal Notation

3.66519 \dots

Solution steps

x \to \frac{π}{3} lim (7 x cos (x))

Plug in the value

x = \frac{π}{3}

= 7 \cdot \frac{π}{3} cos (\frac{π}{3})

Simplify

7 \cdot \frac{π}{3} cos (\frac{π}{3}) : \frac{7 π}{6}

= \frac{7 π}{6}

\frac{d}{d x} (\frac{7}{4 x + 1})

y = e^{3 - x}

y + (x^{2} + y^{2}) d x - x d y = 0

6 x^{2} + (x^{3} + 2) \frac{d}{d x} y = 0

\frac{d}{d x} (\frac{12}{x})
