India’s first e-waste eco park will be developed in Holambi Kalan in Delhi in an area of about 21 acres. ‘e-waste eco park’ refers to the establishment of a place where this e-waste is dismantled, refurbished, recycled, and manufactured in a manner that is scientifically and environmentally sound. Delhi is the fifth-largest producer of e-waste in India, after Maharashtra, Tamil Nadu, Uttar Pradesh and West Bengal. Delhi produces over two lakh tonnes of e-waste every year, or about 9.5 per cent of the total amount produced in India, and only five per cent of the generated e-waste is properly recycled.
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:
