WBJEE 2025 Trigonometry Practice Questions with Solutions

The WBJEE 2025 Trigonometry practice questions with solutions provide an insight into the WBJEE question paper. It serves as a useful resource when preparing for the WBJEE examination. These questions can be used for practicing the fundamentals of the chapter and assessing the knowledge and preparation level. In this section, we have listed some of the WBJEE 2025 Trigonometry practice questions that are frequently asked in the Paper I (Mathematics) and hence, must not be skipped. 

Q1. The equation √3 Sinx + Cosx = 4 has 

a. Infinitely many solutions

b. No solution

c. Two solutions

d. Only one solution

Ans. b. No solution

Solution: 

√3/2 Sinx + 1/2Cosx = 2

Sinx Cos π/6 + Cos x.Sinπ/6 = 2

Sin [x + π/6] = 2

This is not possible because the value of sin x lies between –1 and 1, therefore, no solution

Q2. The principal value of sin-1tan [-5π/4] is

a.  π/4

b. – π/4

c. π/2

d. – π/2

Ans. d. – π/2

Solution:
We need to find sin-1tan [-5π/4]

Step 1: Compute tan(-5π/4)

Since tan(x+π) = tan x, we rewrite:

tan(-5π/4) = tan 3π/4) = -1

Step 2: Compute sin-1 (-1)

We know:

sin-1(-1) = π/2

Final Answer:

-π/2

Q3. The value of cosπ/15 cos2π/15 cos 4π/15 cos 8π/15 is

a. 1/16

b. – 1/16

c. 1

d. 0

Ans. b. – 1/16
Solution:
Using the identity:
A well known identity for products of cosines states:

cosπ/15 cos2π/15 cos4π/15 cos8π/15 = 1/16
However, since one of the angles is in the second quadrant, the product becomes negative:
cosπ/15 cos2π/15 cos4π/15 cos8π/15 = -1/16
Final answer:
-1/16
Q4. The value of tan–1[sin2-1/cos2] is

a. π/2–1

b. 1–π/4

c. 2–π/2

d. π/4–1

Ans. b. 1–π/4

Q5. The solution set of the inequation cos–1x < sin–1x is

a. [-1,1]

b. [1/√2,1]

c. [0,1]

d. (1/√2,1]

Ans. (1/√2,1]

Q6. If a = 2√2, b = 6, A = 45°, then

a. No triangle is possible

b. One triangle is possible

c. Two triangles are possible

d. Either no triangles or two triangles are possible

Ans. a. No triangle is possible

Q7. In triangle ABC, if sin A sin B = ab/c2, then the triangle is

a. Equilateral 

b. Isosceles

c. Right angled

d. Obtuse angled

Ans. c. Right angled
Solution:
Step 1: Using the Since rule:

sin A = a/c, sin B = b/c
Multiplying both:
sinA sinB = a(a/c)(b/c) = ab/c2
This matches the given equation, which means that the equation holds for all values of A and B.
Step 2: Identifying the Triangle type:
The equation is always true when C = 90°
Thus, the triable is right - angled.

Q8. In a triangle PQR, ∠R = π/2. If tan (P/2) and tan (Q/2) are roots of ax2 + bx + c = 0, where a ≠ 0, then which one is true

a. c = a + b

b. a = b + c

c. b = a + c

d. b = c

Ans. a. c = a + b

Q9. If in a triangle ABC, sin A, sin B and sin C are in A.P., then

a. The altitudes are in A.P.

b. The altitudes are in H.P

c. The angles are in A.P.

d. The angles are in H.P.

Ans. b. The altitudes are in H.P.
Solution:
We are given that sin A, sin B, sin C are in A.P.
Step 1: Use A.P. Condition
Since they are in arithmetic progression:
2sinB = sinA + sin C
Using the sine rule in a triable:
sin A = a/2R, sin B = b/2R, sin C = c/2R
Substituting in A.P. condition:
2.b/2R = a/2R + c/2R
2b = a+c
which is the condition for the altitudes ha, hb, hc being in harmonic progression (H.P.)
Final answer: The altitudes are in H.P.
Q10. Let p, q, and r be the altitudes of a triangle with area S and perimeter 2t. Then, the value of 1/p + 1/q + 1/r is
  • a. S/t

  • b. t/S

  • c. S/2t

  • d. 2S/t

Ans. b. t/S
