limit as x approaches 1+of 1-cos(2(x-1))

解答

x \to 1 + lim (1 - cos (2 (x - 1)))

0

求解步骤

x \to 1 + lim (1 - cos (2 (x - 1)))

代入值

x = 1

= 1 - cos (2 (1 - 1))

化简

1 - cos (2 (1 - 1)) : 0

= 0

d er i v a t i v e sin (θ) cos (θ)

\int - sec (x) d x

x \to - 27 lim (\frac{6}{x + 27})

\int_{0}^{- 0.4} 400 x d x

\frac{d}{d x} (\frac{- 2 x ^{3} - 1}{( x ^{3} - 1 ) ^{2}})
