This fact simplifies our task somewhat. Complete the squares in the denominator and rewrite the expression as: **2** ( **1**)23 **2 1** 3 **2** 10 **1** + = s. Its inverse transform is sin(3 ...

### SOLUTION: ASSIGNMENT 5 - UCB Mathematics

**T**(M) = **1 2** 3 6! from R22 to R22. Solution. Denote **1 2** 3 6! as A. For any M1;M2 2R22 and k1;k2 2R, **T**(k1M1 + k2M2) = (k1M1 + k2M2)A = k1M1A + k2M2A = k1T(M1) + k2T(M2) Therefore **T** is linear. **T** is not an isomorphism because A is not invertible. In this case **T** maps any matrix to a non-invertible matrix so imT cannot be R22 (e.g. it avoids all ...
