Question
Each of the following sentences has been divided into
five parts (a), (b), (c), (d), and (e) . One of these parts may contain a grammatical or idiomatic error. Identify the part that contains the error. If there is no error, choose option (e). The committee members (a)agreed with (b)the revised proposal (c)after detailed deliberations (d).No error (e)Solution
Rule: Agree to ā plan, proposal, decision Agree with ā person or opinion Correct usage: agreed to the revised proposal āAgreed with the proposalā is incorrect Error lies in part (b)
What is the simplified value of the given expression?
4(sin² 20° + sin² 70°) + 2sin 30° - (2sec 60° + cot 45°)
If 17sin A = 8, where 0
tan 20Ė x tan 23Ė x tan 67Ė x tan 70Ė = ?
If 3 tan X + cot X = 2ā3, then find the value of 6 tan2Ā X + 2 cot2Ā X.
If 2ycosĪø = x sinĪø and 2xsecĪø ā ycosecĪø = 3, then x 2 + 4y 2 = ?
If (3cos A - sin A) = 2 cos (90° - A), then find the value of cot A.
- Find the maximum value of (9sin A + 12cos A).
- If 2cos²A + 3sin²A = 13/5, then find the value of (sec²A - 1)
- If sin 2a = (1/2), then find the value of (sin a + cos a).
- If sin (3A ā 2B) = (ā3/2) and cos (A + B) = (1/2), where 0° < A, B < 90°, then find the value of āAā.
