A 10-FT LONG ROD HAS BOTH OF ITS ENDS INSULATED DURING HEATING OPERATION. BUT EVEN AT ITS INITIAL OPERATION (T=0), THE ROD IS ALREADY LATERALLY INSULATED. FIND U(X,T) IF THE THERMAL DIFFUSIVITY EQUALS 1.5 (X=5.0)

Solve for complete integral

z=px+qy+c√(1+p²+q²)

Find the complete integral using Charpit Method : p+q=3pq

Solve (1-x^2) y''+2xy'-2y=0, y1=x (one of the solutions)

Consider the relation schema R=(A, B, C, D) with functional dependency F as follows

A BC

B D

D B

Show a decomposition of R into R1 and R2 so that each relation of the decomposition is

in BCNF and also dependency preservation is achieved.

y'' + 14y' + 49y = 0

Solve dy/dx + yx = y2e^(x^2/2)sinx

d^2y/dx^2+9y=3+sin (3x)
