Given 2 subspaces and a linear operator, is the image of the direct sum of the subspaces equal to the union of the images under the operator?
Thanks
Thanks

The direct sum of two vector spaces is a new vector space that combines the elements of both original spaces. In direct sum, the elements from each space are added together, and the resulting vector space contains all possible combinations of these elements.
The union of two vector spaces includes all the elements from both spaces, without any regard for their structure or operations. On the other hand, the direct sum combines the elements in a specific way that preserves the structure and operations of the original spaces.
No, the direct sum and the union are fundamentally different concepts and cannot be equal. The direct sum is a new vector space, while the union is simply a collection of elements from both original spaces.
A linear operator is a function that maps elements from one vector space to another. In the direct sum, a linear operator is used to combine the elements from each space and create the new vector space.
The direct sum is used in various applications, including computer graphics, signal processing, and data compression. It is also a fundamental concept in abstract algebra and can be used to solve problems in linear algebra, geometry, and physics.
