Domestic payment systems like UPI, RTGS, and NEFT fall under RBI's direct oversight.
- If (sin 3A sec 6A = 1) , then what will be the value of cos 6A?
If P, Q, R, S are the vertex of a cyclic quadrilateral. Find the value of
`1/sec p` + `1/sec q` + `1/sec r` +`1/sec s`
...If cosec (2A + B) = (2/√3) and cosec (A + B) = √2, then determine the value of (4A - B).
Determined the simplified value of the given expression:(1 - sin2Â q) X (sec q + tan q) X (sec q - tan q) X cosec2Â q
The value of sec2 45˚ + 2 tan 135˚ is –
cot 4˚ x cot 47˚ x cot 42.3˚ x cot 43˚ x cot 47.7˚ x cot 86˚= ?
If sec A + tan A = 3 and sec A - tan A = (1/3), find the value of cos A.
