Natural farming is defined as a “chemical- free farming and livestock based”. North East India has traditionally been organic, and the consumption of chemicals is far less than the rest of the country. Sikkim is the first state in the world which became a fully organic state. Natural farming is in sync with the Sustainable Development Goal-2. Participatory Guarantee System (PGS) is a process of certifying organic products produced by natural farming. It ensures that their production takes place in accordance with laid-down quality standards.
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:
