duties of the Chairperson of the Rajya Sabha?Solution
The file lists the Deputy Chairman as the person who performs the duties of the Rajya Sabha Chairperson in the Vice President’s absence.Â
∆ PQR is right-angled at Q. If ∠R = 60º, then find the value of cosec P.
If tan² 45°- cos² 60° x sin 45° cos 45° cot 30°, then find the value of 'x'.
The value of (3tan10°-tan³10°)/(1-3tan²10°) is equal to
- If sin (4A − B) = (√2/2) and cos (A + B) = (√2/2), where 0° < A, B < 90°, then find the value of ‘A’.
sin2 7 ° + sin2 8 ° + sin2 9 ° + sin2 10 ° + ……… + sin2 83 ° = ?
...If cos1.5B = sin(B + 5°), then find the measure of 'B'.
- If sin(A + B) = 1/2 and cos(A + 2B) = √3/2, where 0° < A, B < 90°, then find the value of tan(2A).

cos (sec-1 x) is equal to –
If A + B = 450 , then the value of 2(1 + tanA) (1 + tanB) is:
