limit as x approaches 1 of cos(pix)

x \to 1 lim (cos (π x))

- 1

Solution steps

x \to 1 lim (cos (π x))

Plug in the value

x = 1

= cos (π 1)

Simplify

cos (π 1) : - 1

= - 1

\int \frac{cos ( 2 x )}{sin ( 2 x )} d x

x \to 8 lim (\frac{x ^{2}}{4} - \frac{2}{x})

\frac{d}{d x} (\frac{x ^{2} + 4 x + 3}{x})

\frac{d}{d x} (x - b ln (x))

\frac{3 s + 7}{s ^{2} + 4 s + 3}
