If A lies between 45° and 540°, and sin A = 0.5, what is the value of A/3 in degrees?
sin 3 θ+cos3θ = 0, then the value of θ is
If x cosA - y sinA = 1 and x sinA + y cosA = 4, then the value of \(17x^2+17y^2\) is:
If A, B, and C are the angels of a △ABC then the following is equal to :sin\(({B+C \over2})\)
A, B and C can do one-third of a work in 15 days, 30 days and 10 days, respectively. A started the work. C joined him after 1 day and B joined them after 3 days of the beginning. For how many days did C work?
