(x + 2)sinydx + xcosydy = 0 Find the general solution of the equation.

The lengths of two sides of a triangle are measured to be 10 inches and 6 inches. The angle betweer the sides is measured to be 60 degrees. The error in the measurements of the sides is no more than 0.4 inches, and the error in the measurement of the angle is no more than 2.0 degrees. Use differentials to estimate the maximum error is using the formula A = 0.5 ab sin 0 to find the area of the triangle where a is the 10 inch side, b is the 6 inch side, and O is the included angle.

Integrate by the first method or state why it does not apply  and use the second method. Show the details.
