The logic followed here is: Second number = First number - 14 Third number = Second number + 28 In (38, 24, 52) = 38 – 14 = 24; 24 + 28 = 52. (45, 31, 59) = 45 – 14 = 31; 31 + 28 = 59. (44, 30, 58) = 44 – 14 = 30; 30 + 28 = 58. (54, 40, 68) = 54 – 14 = 40; 40 + 28 = 68. (78, 64, 92) = 78 – 14 = 64; 64 + 28 = 92. (92, 40, 68) = 92 – 14 = 78; 78 + 28 = 106.
sin2 9 ° + sin2 10 ° + sin2 11 ° + sin2 12 ° + ……… + sin2 81 ° = ?
...If 4cos2x - 3 = 0, and (0° > x > 90°), then find the value of 'x'.
If tan θ = (2/√5), then determine the value of cos2 θ
If √3cosec 2x = 2, then the value of x:
If x = (sin 30 ° + cos 30 ° )/sec 60 ° , then find the value of 4x.
If sin3A = cos(5A-30°), then what is the value of A? Given that 3A is an acute angle.
If sin x + cos x = √2 sin x, then the value of sin x - cos x is:
Simplify the given equation:
