Mathematical Ex.2 It is read as: Little a times r to the n minus one power plus the cube root of x, equals big A plus B over T, plus T over log R to the base ten. Mathematical Ex.3 The integral from zero to pi over two of dee x over one plus αtimes cosine of x, plus the sum from r equals zero to r equals n of the quantity n things taken r at a time squared, equals the integral from x equals zero to x equals b of the function f of x times dee x The integral from zero to pi over two of the quantity one over one plus αtimes cosine of x with respect to x, plus the sum from r equals zero to r equals n of the quantity n over r at a time squared, equals the integral between the limits x equals zero and x equals b of the function of x with respect to x Mathematical Ex.4 The quantity a plus b to the nth power equals to the nth power plus n times the quantity a to the n minus one power times b plus n times bracket n minus one bracket closed divided by two times the quantity a to the n minus two power times b squared down to b to the nth power Chemical and physical Formulas-1 F E and S react to give F E S S I O two and two C react to form S I and two CO Open bracket N H four close bracket twice C P two O seven Chemical and physical Formulas-2 Two K C L O three, when heated in the presence of a manganese dioxide as a catalyst forms two K C L and releases three O two Two potassium chlorate, in the presence of a manganese dioxide catalyst on heating, forms two potassium chlorate and releases three oxygen Chemical and physical Formulas-3 Six N H four O H plus A L two open bracket S O four close bracket three times yield two A L open bracket O H close bracket three times plus three open bracket N H four close bracket twice S O four When ammonium hydroxide is added to a solution of aluminum sulfate, aluminum hydroxide and ammonium sulfate are formed Chemical and physical Formulas-4 C H four and two O two react to give C O two and two H two Methane reacts with
