need help with 6 &7

6. Determine the normalization constant K for the one-dimensional wavefunction (x)=Ke3x2. Hint: Use the Resource section of your textbook. 7. Assume the wavefunctions 1(x) ans 2(x) are two orthonormalized solutions of the Schrdinger equation, i.e. they satisfy the follwing relationship: 1(x)1(x)dx=2(x)2(x)dx=11(x)2(x)dx=0 Calculate the normalisation constant N for the wavefunctions: a) 1(x)=N(1+2) b) 2(x)=N(41+2)
