Determine whether each of the equations in problems is exact and find the solution.1) (e^(x)siny+3y)dx-(3x-e^(x)siny)dy=02) (ye^(xy)cos2x-2e^(xy)sin2x+2x)dx+(xe^(xy)cos2x-3)dy=0x>0, y>04) dy/dx=-ax+by/bx+cy5) x dx/((x^(2)+y^(2))^(3/2) + y dy/((x^(2)+y^(2))^(3/2)=0I attached the document and it has the 1 to 5 in it…if you having problem reading it.thanks
