If `a = cos (2012 pi), b = sec (2013 pi) and c = tan (2014 pi)` then

The value of 4 cos(pi/10)-3 sec(pi/10)- 2 tan(pi/10) is equal to

The value of 4 cos(pi/10)-3 sec(pi/10)- 2 tan(pi/10) is equal to

4sin ((pi) / (6)) sin ^ (2) ((pi) / (3)) + 3cos ((pi) / (3)) tan ((pi) / (4)) + cos e ^ ( 2) ((pi) / (2)) = 2sec ^ (2) ((pi) / (4))

If A+B+C=pi and cos A=cos B cos C then tan B tan C is equal to

Thevalueof | - (cot pi) / (32) + (tan pi) / (32) +2 (tan pi) / (16) +4 (tan pi) / (8) | = (A) 4 (B) 8 (C) 16

If A+B+C=pi and cos A= cos B.cos C prove that tan A= tan B+ tan C

If A+B+C=pi & cos A = cos B . Cos C then tan B . Tan C has the value equal to

If sin A = 3/5, tan B = 1/2 and pi/2 lt A lt pi and pi lt B lt (3pi)/(2) then 8 tan A - sqrt(5) sec B =
