MA1506 TUTORIAL 1 1. 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}. [curly brackets for the initial conditions‚ with x followed by y.] Here dy represents

Let us examine the following condition of complete observations given above. Assume that $\Upsilon_{\chi}$ is taken as distribution function whose total failure times is studied using gamma distribution applied to the shape parameters $3$ together with scale parameters $2.$ On side of repair time it goes with the same way failure time with gamma distribution together with shape parameter $1‚$ and scale parameter $2$ respectively. The time $\tau$ is examined as the following $\tau=2.5‚\tau=5‚$ and
