Question
Sunaina said, âI went to the school
yesterdayâ. In the following question, a sentence has been given in Direct/Indirect speech. Out of the four alternatives suggested, select the one which best express the same sentence in Indirect/Direct speech.Solution
The correct answer is B
cot 13Ë Â
 cot 14Ë Â ...If (sin A + cos A) = â3 cos (90° - A), then find the value of cot A.
- If 2cos²A + 3sin²A = 13/5, then find the value of (sec²A - 1)
If sin (2x + 50) o = cos (2y - 50) o, such that, 0o < x + y < 90o, then find the value of tan(x + y) .
- If sin(A + B) = â3/2 and cos(A + 2B) = 0, where 0° < A, B < 90°, then find the value of tan(2A).
If cos 2A = 1, then find cos A
What is the simplified value of the given expression?
3(sin² 50° + sin² 40°) + 6sin 30° - (3sec 60° + cot 45°)
Find the value of `1/2`  cosec 10  - `2/(cosec 70)`  ?
Find the maximum value of 20 sin A + 9 cos A.
- If sin (3A â 4B) = (1/2) and cos (A + B) = (â2/2), where 0° < A, B < 90°, then find the value of âAâ.
