(1) Find the area between the curve y= - 2x3+ 21 x - 45 x and the X-axis from X= 2 to X= 6. 2Ja). Check that the Ist order differential equations 3X IX - of - 3 4 - 10 (5 / xyt ) is homogenous and hence solve it by substitution. ( express y in term of x ) b) Find the particular solution it g ( 1 ) = 32
