limit as x approaches pi/2 of cos(2x)

x \to \frac{π}{2} lim (cos (2 x))

- 1

Solution steps

x \to \frac{π}{2} lim (cos (2 x))

Plug in the value

x = \frac{π}{2}

= cos (2 \cdot \frac{π}{2})

Simplify

cos (2 \cdot \frac{π}{2}) : - 1

= - 1

\int_{0}^{10} x 10 - x d x

y = (x^{2} + 1) (x^{2} - 2 x)

ln (1 - x^{2})

\int (x^{2} + 2 x - 3) d x

\int_{0}^{1} \frac{1 + 12 t}{1 + 3 t} d t
