Find y in terms of x for the equation 2x(dy/dx) + 4y = 8x^2

divide through by 2x to get: dy/dx + 2y/x = 4x         this is now in the form of dy/dx + P(x)y = Q(x)

F ind all values of x in the range 0° <= x <= 180° satisfying tan(x+45°)= 8tan(x)

tan(x)+tan(45)/1-tan(x)tan(45) = 8tan(x)

8tan2(x)-7tan(x)+1=0

tan(x)=0.6952 or 0.1798

x = arctan(0.6952) = 34.8070 deg and arctan(0.1798) = 10.1932 deg
