National Farmers' Day, or Kisan Diwas, is celebrated across the country on 23 December to honour India's farmers and mark the birth anniversary of the nation's fifth Prime Minister, Choudhary Charan Singh. Chaudhary Charan Singh, the Kisan Leader, served the country for a very short period from July 28, 1979, to January 14, 1980. He followed the famous slogan - "JAI JAWAN JAI KISAN" which was given to the farmers by Lal Bahadur Shastri, the second Prime Minister of India.
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:
