C sits third to the right of A. One who is sitting opposite to C sits immediate left of H Case-1 Case-2
Only one person sitting between H and J. J is sitting one of the right positions of H. Only two people are sitting between J and I. Case-1
One who is sitting opposite to G sits third to the left of B. Case-1
But B is not sitting at the extreme ends. Since Case (2) is not possible. Case-1
Number of persons sitting to the left of F and number of persons sitting to the Left of E is same. So the final arrangement is Case-1
If cot5A = tan(3A-14˚), find the value of A? Given that 5A and 3A-14˚ are acute angles.
Find the value of sin 30°.
If A + B = 450 , then the value of 2(1 + tanA) (1 + tanB) is:
If 9 sinx + 40 cosx = 41 then find tanx.
If tan A = 4/3, 0 ≤ A ≤ 90°, then find the value of sec A.
Simplify: sin 780° sin 480° + cos 120° sin 30°
sin2 12˚ + sin2 14˚ + sin2 16˚ + sin2 18˚ + ……… + sin2 78˚ =?
What is the value of 1/(1+tan 2θ ) + 1 / (1+cot 2 θ ) = ?
...If 2x = cosec @ and 4/x = cot @ then the value of 2(x ² - 1/x ² ) is
