Solve the following differential equations: (a) x(x + 1)y = 1 (b) (sec(x))y = cos(5x) (c) y = e(x−3y) (d) (1 + y)y + (1 − 2x)y 2 = 0 Use www.graphmatica.com to sketch the functions you found as solutions of [a]-[d]‚ if y = 1/2 at x = 1. Graphmatica can also directly sketch the graph if you insert the equation itself; for example‚ in [a] you just enter x(x + 1)dy = 1 {1‚ 1/2}.

Mathematics Assignment 153. Explain the negative exponent rule and give an example. The main rule for a negative exponent is to always first make it into a positive before you start simplifying. For example y^-4+7=x The first thing you would do is write it as this 1/y^4+7=x Once this is completed you can then simplify. 154. How do you know if an exponential expression is simplified? You can tell if an exponential expression is simplified when it brought down to the lowest possible simplification
