India's first underwater metro service, the East-West Metro Corridor project will be completed by December 2023. Kolkata Metro started its journey in 1984, and is being expanded to cover the whole city and its outskirts. The East-West corridor of the Kolkata Metro is 15 Km-long and spans from Salt Lake Stadium to Howrah. The project will connect the busy Howrah and Sealdah railway stations as well as the north-south line of the Kolkata Metro at Esplanade.

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:
