Answer:
Show me the options
Step-by-step explanation:
X = y
y = 4
By the substitution property, we can replace y with 4 in that first equation.
x = 4
Answer:
C
Step-by-step explanation:
Since this is an indererminate form, use L'Hopital
d(sint)/dt = cos(t)
d[ln(2e^t) - 1] = (2e^t)/[2e^t - 1]
As t --> 0,
cos(0) = 1
(2e^t)/[2e^t - 1] = 2
1/2 is the limit
