AP Inter 2nd Year Maths Important Questions 2026-27

Scoring full marks in Class 12 board exams requires a clear plan and the right study material. Mathematics is a scoring subject where students can secure 75 out of 75 marks in both Paper IIA and Paper IIB if they practice standard question models regularly. Students preparing for AP Intermediate 2nd Year should follow a structured revision schedule covering both algebra and calculus comprehensively.

The AP Board 2nd Year Maths Important Questions are structured around the official blueprint issued by the Board of Intermediate Education, Andhra Pradesh. The exam is divided into two separate papers: Mathematics IIA (Algebra, Probability, and Statistics) and Mathematics IIB (Coordinate Geometry and Calculus), each carrying 75 marks. Students should regularly monitor the AP Inter Time Table 2027 to map out their study routine according to the official timetable.

AP Inter 2nd Year Maths Important Problems

Here are two essential problems with step-by-step solutions that regularly appear in the board exams.

Problem 1: De Moivre’s Theorem Proof

Question: If n is an integer, show that (1+i)2n+(1-i)2n=2n+1n2.

Solution:

1. Convert 1+i into polar form:

1+i=24+i4

2. Apply index 2n:

(1+i)2n=24+i42n=2n2n4+i2n4=2nn2+in2

3. Similarly, for 1-i:

(1-i)2n=2nn2-in2

4. Adding both expressions:

(1+i)2n+(1-i)2n=2n2n2=2n+1n2

Hence proved.

Problem 2: Orthogonal Circles

Question: Find the value of k if the circles x2+y2+4x+8=0 and x2+y2-16y+k=0 are orthogonal.

Solution:

1. Compare with the standard circle equation x2+y2+2gx+2fy+c=0:

• Circle 1: g1=2, f1=0, c1=8

• Circle 2: g2=0, f2=-8, c2=k

2. The condition for two circles to cut orthogonally is:

2g1g2+2f1f2=c1+c2

3. Substitute the values:

2(2)(0)+2(0)(-8)=8+k

$$0 = 8 + k \implies k = -8$$
