Can someone help me with these three equatons. They have to solve with matlab code. Here are : 1. y'' - y = 0 y(0)=0 y(1)=1 2. y''-y=-4(sin^3)x + 9sinx y(0) = y(2*pi) 3. Ut=Uxx + U + 2sin2xsinx U = U(x,t) where x is (0;pi/2) and t >0 Thnak you in advance!

Can someone help me with these three equatons. They have to solve with matlab code.

Here are :

y'' - y = 0

y(0)=0

y(1)=1

y''-y=-4(sin^3)x + 9sinx

y(0) = y(2*pi)

Ut=Uxx + U + 2sin2xsinx

U = U(x,t) where x is (0;pi/2) and t >0

Thnak you in advance!
