limit as h approaches 0 of (sqrt(49+h)-7)/h

h \to 0 lim (\frac{49 + h - 7}{h})

\frac{1}{14}

Decimal

0.07142 \dots

Solution steps

h \to 0 lim (\frac{49 + h - 7}{h})

Rationalize numerator

\frac{49 + h - 7}{h} : \frac{1}{h + 49 + 7}

= h \to 0 lim (\frac{1}{h + 49 + 7})

Plug in the value

h = 0

= \frac{1}{0 + 49 + 7}

Simplify

\frac{1}{0 + 49 + 7} : \frac{1}{14}

= \frac{1}{14}

2 \cdot sin (3 t)

y = e^{3 x}, y = e^{- 3 x}, x = - 1

\frac{d}{d x} (\frac{e ^{\frac{7 x}{4}}}{1 - 9 x ^{2}})

\int_{0}^{2} - 6 x^{3} x^{2} + 4 d x

\frac{d}{d x} (1 + x + 5 x^{2})
