周期性 f(x)=(sec(pix))/2

解答

周期性

f (x) = \frac{sec ( π x )}{2}

2

求解步骤

周期

sec (b x + c) + d = \frac{sec ( x ) 的周期}{∣ b ∣}

sec (x)

的周期是

2 π

= \frac{2 π}{∣ π ∣}

化简

= 2

p a r i t y 2 x^{6} + x^{8} + 3

s l o p e in t erce pt 3 x

d o main \frac{ln ( x - 1 )}{( x - 1 ) ^{3}}

y = 4 x

in t erce pt s f (x) = (x - 1) (x - 3)
