    To do this. cosec(x) - 1/2x - 1 = f(x) Let f(x) = 0 Then put f(0.5) and f(1) then one wwill be < 0 and one will be > 0 so it means root lies b/w this points.

    AZ = 5cos(0.6) AQ = 5 ZQ = AQ - AZ = 5 - 5c0s(0.6) = 0.8733 ZP = ZQ = 0.8733 so PQ = 0.8733 + 0.8733 = 1.75

    Two coordinates of P and Q common will be (0,0) and other of P (acos^4t,0) and other of Q (0,asin^4t) Use As level distance between two coordinates formula that is sqrt of ((x2 - x1)^2 + (y2 - y1)^2) You will get asin^2t + bsin^2t = OQ + OP = a

    The atomic mass of an element, measured in amu, is the same as the mass in grams of one mole of an element. To convert gram to kilogram we should divide the mass by thousand so 90/1000 = 0.09 kg.

    1 mol -----------> avogedro number N ? <---------------- 4.67 x 10^15 N m = n * Mr Mr = 0.09kg n = 7.76 x 10^-9 m = 6.98 x 10^-10 kg.
