FAQs on Trigonometry Mock Test for JEE Main 2025-26: Ultimate Practice & Preparation
1. What is trigonometry and why is it important for students in Class 10, NDA, SSC CGL, and other competitive exams?
Trigonometry is a branch of mathematics that studies the relationships between the sides and angles of triangles. It is fundamental in solving problems involving heights and distances, and forms the basis for advanced topics in mathematics, physics, and engineering. Mastery of trigonometric ratios, formulas, and identities is vital for success in Class 10, Class 11, NDA, SSC CGL, JEE, and other competitive exams as it develops logical reasoning and analytical skills.
2. What are the basic trigonometric ratios and their definitions?
The basic trigonometric ratios are sine (sin), cosine (cos), and tangent (tan). For a right-angled triangle with angle θ:
• sin θ = Opposite side/Hypotenuse
• cos θ = Adjacent side/Hypotenuse
• tan θ = Opposite side/Adjacent side
These ratios help in understanding the relationships among the sides and angles.
3. What are the trigonometric values for standard angles (0°, 30°, 45°, 60°, 90°)?
Standard angle trigonometric values are crucial for quick calculations. Key values:
• sin 0°=0, sin 30°=1/2, sin 45°=1/√2, sin 60°=√3/2, sin 90°=1
• cos 0°=1, cos 30°=√3/2, cos 45°=1/√2, cos 60°=1/2, cos 90°=0
• tan 0°=0, tan 30°=1/√3, tan 45°=1, tan 60°=√3, tan 90°=undefined
4. How do you solve heights and distances problems using trigonometry?
To solve heights and distances questions:
1. Draw a diagram and mark known and unknown values.
2. Identify the right triangle formed by the height, base, and line of sight.
3. Use appropriate trigonometric ratios (sin, cos, tan) based on the information given.
4. Substitute values and solve for the missing quantity, ensuring all measurements use the same unit. This approach is common in Class 10 Board, NDA, and competitive exam questions.
5. What are some key trigonometric identities for class 10 and 11 exams?
Essential trigonometric identities include:
• sin²θ + cos²θ = 1
• 1 + tan²θ = sec²θ
• 1 + cot²θ = cosec²θ
These identities are frequently used to simplify and solve trigonometry problems in class 10, 11, and competitive exams.
6. What is the best technique to remember trigonometric ratios and signs in different quadrants?
To remember trigonometric ratios and signs:
• Use the mnemonic “All Students Take Coffee” to recall sign distribution by quadrants:
- First quadrant: All positive
- Second: Sine positive
- Third: Tangent positive
- Fourth: Cosine positive
• Practice standard angle values regularly.
• Apply these when dealing with trigonometric equations or transformations.
7. How can I prepare for trigonometry questions in JEE or SSC CGL exams?
Preparation includes:
• Understanding all basic and advanced trigonometric concepts
• Practicing with mock tests, previous year questions, and sample papers
• Memorizing key formulas and identities
• Working on speed and accuracy for multiple-choice questions
• Reviewing mistakes after every test.
Consistent practice with a variety of question types is crucial for exams like JEE and SSC CGL.
8. What is meant by complementary angles in trigonometry?
Complementary angles are two angles whose sum is 90°. In trigonometry, the ratios are related as follows:
• sin (90° – θ) = cos θ
• cos (90° – θ) = sin θ
• tan (90° – θ) = cot θ and so on.
This concept is applied in various board and competitive exam questions.
9. How do you find the unknown side or angle in a right-angled triangle?
To find the unknown side or angle:
• Identify the given sides and the required side or angle.
• Choose the correct trigonometric ratio (sin, cos, or tan) for the known values.
• Set up the equation and solve for the unknown.
• For missing angles, use the inverse trigonometric function if required.
10. Are calculators allowed in trigonometry exams for Class 10, NDA, SSC CGL, or JEE?
In most school board exams (including CBSE Class 10/11/12) and competitive exams like NDA, SSC CGL, and JEE Main, calculators are not allowed. Students must practice solving problems manually and memorize important trigonometric values and identities to improve speed and accuracy.
11. What common mistakes should be avoided while solving trigonometry problems?
Common mistakes include:
• Confusing opposite and adjacent sides
• Using incorrect trigonometric ratio
• Forgetting to convert degrees and radians
• Calculation errors with standard angle values
• Ignoring the quadrant sign rules
Regular practice can help overcome these errors.
12. Where can I download trigonometry practice tests and mock test PDFs with solutions?
Trigonometry practice tests and mock test PDFs with answers/solutions can be downloaded from:
• Vedantu (official website/app)
• NCERT and CBSE portals
• Other reliable educational websites providing
– Class 9, 10, 11, 12 practice sets
– NDA, SSC CGL, JEE sample papers
Always refer to the latest syllabus and answer keys while practicing.
