Recently, the Climate Club was formally launched at the 28th Conference of Parties (COP28) to the United Nations Framework Convention on Climate Change. It is led by Germany and Chile, the Club has garnered support from 36 member countries including Kenya, the European Union, Switzerland and others. It aims to make decarbonization of industries successful for climate and businesses, through ambitious policies. Currently, Organisation for Economic Co-operation and Development and International Energy Agency are the joint interim heads of secretariat.
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:
