Class 10 Maths trigonometry test

The sine, cosine and tangent values at 0, 30, 45, 60 and 90 degrees - fifteen figures in total, with some repeating and others mirroring, which is why examiners draw heavily from them in short-response questions. Every other part of the chapter rests on secure knowledge of this table.

The prefix 'Co' means complement. Cosine represents the sine of the complementary angle, cosecant represents the secant of the complementary angle, and cotangent represents the tangent of the complementary angle. Recognising this pattern clarifies why sin(90-A)=cos A and eliminates the need to memorise the remaining pairs independently.

Absolutely, it is entirely free with no registration required. There is no need for an email address, user account or login credentials. The test operates within your browser without retaining any information, and the score remains visible only in that session before vanishing when you close the browser tab. Our privacy policy reflects this practice directly rather than asking for your confidence.

Timing is optional and disabled initially. A first go should reveal what a child truly understands, not the pace at which they work when observed. When timed mode is enabled, approximately ninety seconds per question matches the board exam speed for objective-type questions.

Repeatedly if desired. The question bank ensures variety, and each attempt reshuffles both the sequence and the answer options, making it impossible to succeed through memorisation. During board year exams, periodic retakes guided by your revision checklist prove more beneficial than a single extended study session.

Paper worksheets concentrate on one chapter intensively and you score them yourself; tests automatically score and mix chapters like a real exam does. A test identifies the gap, worksheets then fill it—families typically find ten minutes here yields more gain than an hour practising something that never was the real difficulty.
