Exam-Style Questions.Problems adapted from questions set for previous Mathematics exams. |
1. | IB Standard |
The acceleration, \(a\) ms-2 , of an object at time \(t\) seconds is given by
$$a=\frac1t+4sin3t, (t\ge1)$$The object is at rest when \(t=1\).
Find the velocity of the object when \(t=7\).
2. | IB Analysis and Approaches |
Given that \( \frac{dy}{dx} = \sin(x + \frac{\pi}{3})\) and \(y = 5\) when \(x = \frac{8\pi}{3}\), find \(y\) in terms of \(x\).
3. | A-Level |
(a) Using a suitable substitution, or otherwise, find
$$ \int \frac{x}{(3x^2 - 5)^2} dx$$(b) Solve the differential equation below giving your answer in the form \(y = f(x)\). It is given that given that y = \( \frac{1}{2} \) when x = 0.
$$ \frac{dy}{dx} = \frac{2xy^3}{(3x^2 - 5)^2}$$4. | IB Analysis and Approaches |
Find \(f(x)\) if:
$$ f'(x) = \frac{12x}{\sqrt{3x^2+4}}$$given that \(f(0) = 10 \)
5. | IB Analysis and Approaches |
Let \(f(x) = \frac{ln3x}{kx} \) where \( x \gt 0\) and \( k \in \mathbf Q^+ \).
(a) Find an expression for the first derivative \(f'(x) \).
The graph of \(f\) has exactly one maximum point at P.
(b) Find the x-coordinate of P.
The graph of \(f\) has exactly one point of inflection at Q.
(c) Find the x-coordinate of Q.
(d) The region enclosed by the graph of \(f\), the x-axis, and the vertical lines through P and Q has an area of one square unit, find the value of \(k\).
If you would like space on the right of the question to write out the solution try this Thinning Feature. It will collapse the text into the left half of your screen but large diagrams will remain unchanged.
