given that y = 1 when x = π, find y in terms of x for the differential equation, dy/dx = xycos(x)

y -1 dy = xcos(x) dx∫y -1 dy = ∫xcos(x) dx ln(y) = ∫xcos(x) dx [using integration by parts to integrate the right hand side] therefore, ln(y) = xsin(x) - ∫sin(x) dxln(y) = xsin(x) + cos(x) + cat y = 1, x = π...

Work out 2 3/4 x 1 1/2. Give your answer in terms of a mixed fraction in simplest form.

Step one: As the fractions are mixed fractions we need to convert them into top heavy fractions to multiply. 2 3/4 is equivalent to 11/4 ( as 2 3/4 = 4/4 + 4/4 + 3/4 = 11/4). 1 1/2 is equivalent to 3/2 (as 1...
