Mathematics MCQs
Practice Mathematics multiple-choice questions for UET Lahore competitive exams. Each question includes the correct answer and a short explanation, and past-paper questions are marked so you can revise both repeated and fresh material in one place.
cos(x^2)
2x cos(x^2)
x cos(x^2)
2 cos(x^2)
ExplanationUsing the chain rule, the derivative of sin(u) is cos(u) * du/dx. Here, u = x^2, so the derivative is cos(x^2) * 2x.
Invertible
Singular
Identity
Orthogonal
ExplanationA matrix is defined as singular if its determinant is zero, meaning it does not have an inverse.
sin(x) + C
-sin(x) + C
tan(x) + C
-cos(x) + C
ExplanationThe integral of cosine is sine because the derivative of sine is cosine.
2
3
4
8
ExplanationSince 2 raised to the power of 4 equals 16, log base 2 of 16 is 4.
-2/3
2/3
3/2
-3/2
ExplanationThe slope of 2x + 3y = 5 is -2/3. The perpendicular slope is the negative reciprocal, which is 3/2.
2
3
4
5
Explanationf(1) = 1^2 + 1 = 2. Then f(2) = 2^2 + 1 = 5.
360 degrees
540 degrees
720 degrees
900 degrees
ExplanationThe sum of interior angles is (n-2) * 180. For n=5, (3)*180 = 540.
0
1
Between 0 and 1
Infinity
ExplanationA circle is a special case of an ellipse where the foci coincide, resulting in an eccentricity of 0.
x = 5, x = -1
x = 5, x = 1
x = 10, x = -2
x = 2, x = -6
Explanation2x - 4 = 6 implies 2x = 10 (x=5); 2x - 4 = -6 implies 2x = -2 (x=-1).
sqrt(4)
sqrt(-1)
0
3.14
ExplanationThe square root of a negative number is defined as an imaginary unit (i).
16
24
20
22
ExplanationSolving the system: 2x=12 -> x=6. Then 6+y=10 -> y=4. xy = 6*4 = 24.
All real numbers
All positive real numbers
All non-negative real numbers
x > 0
ExplanationThe absolute value of any real number is always greater than or equal to zero.
0
1
Infinity
Undefined
ExplanationThis is a standard trigonometric limit known as the fundamental limit of sine.
e^x
1/x
x
ln(x)
ExplanationThe derivative of the natural logarithm function ln(x) is 1/x.
60
120
24
30
ExplanationTotal letters = 5, with two P's. Formula: 5! / 2! = 120 / 2 = 60.
