limit as x approaches a of [2f(3)-3g(4)]

解答

x \to a lim ([2 f (3) - 3 g (4)])

2 f (3) - 3 g (4)

求解步骤

x \to a lim (2 f (3) - 3 g (4))

x \to a lim c = c

= 2 f (3) - 3 g (4)

y^{'} (t)

u \to 0 lim (6 - u^{2})

\int \frac{sin ( θ )}{cos ^{3} ( θ ) + cos ( θ )} d θ

d er i v a t i v e cos (2 t)

x \to - 3 lim (- x^{2} + 5 x - 1)
