Some content from latest CBSE Sample Paper and Marking Scheme of Class 12 Maths:
Mathematics Time allowed: 3 hours, Maximum Marks: 100
1. All questions are compulsory.
2. This question paper contains 29 questions.
3. Questions 1 – 4 in Section A are very short-answer type questions carrying 1 mark each.
4. Questions 5 – 12 in Section B are short-answer type questions carrying 2 marks each.
5.Questions 13 – 23in Section Care long-answer I type questions carrying 4 marks each.
6.Questions 24 – 29 in Section D are long-answer II type questions carrying6 marks each.
Q1. If A and B are invertible matrices of order 3, |A| = 2 and | (AB)‒1| = ‒1/6. Find |B|.
| 1/ (AB)| = ‒1/6 ⇒ 1/(|A||B|) = ‒1/6 ⇒ |B| = ‒3. 
Q2. Differentiate sin2(x2) w.r.t x2.
2 sin(x2) cos (x2) or sin (2x2). 
Q3. Write the order of the differential equation: log (d2y/dx2) = (dy/dx)3 + x.
Question4. Find the acute angle which the line with direction cosines 1/√3, 1/√6, n makes with positive direction of z-axis.
l2 + m2 + n2 = 1 ⇒(1/√3)2 + (1/√6)2 + n2 = 1 ⇒ cos γ = 1/√2 ⇒ γ = 45o or π/4. 
Question4. Find the direction cosines of the line: (x ‒ 1)/2 = ‒ y = (z + 1)/2.
Direction ratios of the given line are 2, –1, 2. [1/2]
Hence, direction cosines of the line are:
2/3, ‒1/3, 2/3 or ‒2/3, 1/3, ‒2/3 [1/2]
