limit as x approaches 1 of 4x^3-x^2+7x

x \to 1 lim (4 x^{3} - x^{2} + 7 x)

10

Solution steps

x \to 1 lim (4 x^{3} - x^{2} + 7 x)

Plug in the value

x = 1

= 4 \cdot 1^{3} - 1^{2} + 7 \cdot 1

Simplify

= 10

\frac{d}{d x} (\frac{1 + csc ( x )}{1 - csc ( x )})

\int cos^{2} (4 x) sin^{3} (4 x) d x

x \to \infty lim (7^{2 x})

x^{4} + 4 x^{2} - x

\frac{d ^{2}}{d x ^{2}} (sin (7 x))
