Question 3. ∫ sin(log x) dx
A. (x/2)[sin(logx) - cos(logx)]
B. cos(logx) - x
C. ∫ (x-1)ex / (x+1)3
D. - cos logx
Answer. A
∫ (1 - cosx) dx = x - sin(x) + C₁
u = cos(x) du = -sin(x) dx
Simplifying:
A. (-∞, 1)
B. (-∞, 1) U (2,∞)
C. (-∞,-∞ )
D. (2,∞)
Answer. B
Solution. To determine whether the function f(x) = 2x^3 - 9x^2 + 12x + 29
is monotonically increasing in an interval, we need to analyze the first
derivative of the function, which is given by:
To find the critical points of the function (where the derivative is equal to
zero), we need to solve the equation f'(x) = 0:
6x^2 - 18x + 12 = 0
x^2 - 3x + 2 = 0
(x - 1)(x - 2) = 0
Now we need to analyze the sign of the derivative in the different intervals:
For x < 1, we can choose x = 0 as a test point. Plugging this into the
derivative, we get:
Since f'(0) > 0, the derivative is positive in the interval (-∞, 1). This means
that the function is monotonically increasing in this interval.
For 1 < x < 2, we can choose x = 1.5 as a test point. Plugging this into the
derivative, we get:
Since f'(1.5) < 0, the derivative is negative in the interval (1, 2). This means
that the function is not monotonically increasing in this interval.
For x > 2, we can choose x = 3 as a test point. Plugging this into the
derivative, we get:
Since f'(3) > 0, the derivative is positive in the interval (2, ∞). This means
that the function is monotonically increasing in this interval.
