Answer:
The limit of the function at x approaches to
is
.
Step-by-step explanation:
Consider the information:

If we try to find the value at
we will obtained a
form. this means that L'Hôpital's rule applies.
To apply the rule, take the derivative of the numerator:

Now, take the derivative of the denominator:

Therefore,



Since, tangent function approaches -∞ as x approaches to 
, therefore, the original expression does the same thing.
Hence, the limit of the function at x approaches to
is
.
Answer:
The answer is x=2i√5,−2i√5
Answer:
1.38 to the nearest hundredth.
Step-by-step explanation:
Dividing:
x + 1 ) 3x - 1 ( 3
3x + 3
-4
so (3x - 1) / (x + 1) = 3 - 4 / x+ 1
Integral of (3 - 4 / x+1 ) = 3x - 4 ln(x + 1)
Between limits of 1 and 2 we have:
(3(2) - 4 ln 3) - (3 - 4 ln2)
= 1.6056 - 0.2274
= 1.3782.
