Question 1

Find the differential of the function f(x, y) = ln cos(xy).
◦ cot(xy)(y dx + x dy)
◦ -tan(xy)(y dx + x dy)
◦ tan(xy)(y dx + x dy)
◦ -tan(xy)(x dx + y dy)
◦ -cot(xy)(y dx + x dy)

Question 2

The area of a triangle is given by the formula A =

ab sin θ, where θ is the angle between the sides having lengths a and b. If measurements indicate that a = 4 m with error ± 1 cm, b = 3 m with error ± 1 cm, and θ = 60° with error ± 2°, use differentials to determine the approximate maximum error in the calculated area of the triangle.
◦ about 0.014 m²
◦ about 0.135 m²
◦ about 0.603 m²
◦ about 6.015 m²
◦ about 0.862 m²
