Program Explanation Given information: The differential equation is, d y d x + y 2 = 1 + x 2 One particular solution of Riccati equation is y 1 ( x ) = x . Explanation: The Riccati equation is, d y d x = A ( x ) y 2 + B ( x ) y + C ( x ) The given differential equation can be written as, d y d x = 1 + x 2 − y 2 Consider x + 1 v as y and differentiate with respect to x . 1 − 1 v 2 d v d x = d y d x Substitute 1 − 1 v 2 d v d x for d y d x in given differential equation. 1 − 1 v 2 d v d x = 1 + x 2 − y 2 − 1 v 2 d v d x = x 2 − y 2 1 v 2 d v d x = y 2 − x 2 = ( y − x ) ( y + x ) The value of y − x is calculated as, y = x + 1 v y − x = 1 v The value of y + x is calculated as, y = x + 1 v y + x = 2 x + 1 v Now, the given differential equation can be written as, 1 v 2 d v d x = 1 v ( 2 x + 1 v ) = 2 x v + 1 v 2 d v d x = 2 x v + 1 d v d x − 2 x v = 1 The above equation is a linear first-order equation and its solution is calculated as, v e − 2 ∫ x d x = ∫ e − 2 ∫ x d x d x + C v e − 2 ⋅ x 2 2 = ∫ e − 2 ⋅ x 2 2 d x + C v e − x 2 = ∫ e − x 2 d x + C Simplify the above equation

Rylee's car is stuck in the mud. Roman and Shanice come along in a truck to help pull her out. They attach one end of a tow strap to the front of the car and the other end to the truck's trailer hitch, and the truck starts to pull. Meanwhile, Roman and Shanice get behind the car and push. The truck generates a horizontal force of 377 lb on the car. Roman and Shanice are pushing at a slight upward angle and generate a force of 119 lb on the car. These forces can be represented by vectors, as shown in the figure below. The angle between these vectors is 20.2°. Find the resultant force (the vector sum), then give its magnitude and its direction angle from the positive x-axis. 119 lb 20.2° 377 lb
