Homework 1 Due Monday‚ September 17th at the beginning of class. Show your work. 1. Match the differential equation in (a)-(c) to a family of solutions in (d)-(f). The point of this exercise is not to solve the differential equations in a) - c). (a) y = y 2 (b) y = 1 + y 2 (c) yy = 3x (d) y = tan(x + C) (e) 3x2 − y 2 = C (f) y = −1/(x + C) 2. Find the value of k so that y = e3t + ke2t is a solution of y − 2y − 3y = 3e2t . 3. Solve the following differential equations and IVP’s. You may solve these

The symbols in "In the Heat of the Night" are heat‚ night‚ wallet‚ murder weapon and the colours black and white. The strongest and most significant symbols are heat and night. The heat represents the features of anxiety‚ nervousness‚ and tension. It also suggests to the overall mood of characters. The heat has been repeated several times in the duration of the novel. This symbol is showcased on page one‚ stating "The heat of the Carolinas in August hung thick and heavy in the air." On page two saying

In this experiment‚ the Independent Variable was the heat lamp‚ and the dependent variable was the temperature of the soil‚ because the temperature varied based on whether the heat lamp was turned off or on‚ and whether there was extra water added or not. Our hypothesis was proven correct‚ because the dry soil’s temperature was hotter than the damp soil’s temperature when the heat lamp was on‚ but then it decreased when it turned off‚ while the damp soil’s temperature remained the same. This is because

Heat build-up is one of the most commonly reported issues with post-mastectomy products. Although there is a wide range of products that claim to solve the heat build-up problem‚ many of them are not properly tested by a scientific performance evaluation method. This creates discomfort for the wearers who already suffered enough from the mastectomy experience. The purpose of this study is to introduce both a newly designed heat-reduction mastectomy bra for the clothing comfort and a performance evaluation

Conduction‚ Convection‚ and Radiation The three types of heat transfers are Conduction‚ Convection‚ and Radiation. Heat always moves from a warmer place to a cooler place. For example hot objects that are in a room that is cooler than the temperature of the object will eventually cool to room temperature. First is conduction‚ conduction is heat transferring through direct contact of substances. Then convection‚ which is the transfer of heat by the movement of the warmed matter. Lastly
