If , show that . Interpret the result geometrically?
Given that,
Find the value of .
Take .
[∵ ]
…(i)
[∵ by anti-commutative law, ]
Now, take .
[∵ ]
…(ii)
[∵ by anti-commutative law, ]
From equations (i) and (ii), we have
Now, let us interpret the result graphically.
Let there be a parallelogram ABCD.
Here, and .
And AB and AD sides are making angle θ between them.
Area of parallelogram is given by,
Area of parallelogram = Base × Height
So from the diagram, area of parallelogram ABCD can be written as,
Or,
Since, parallelogram on the same base and between the same parallels are equal in area, so we have
This also implies that,
Thus, it is represented graphically.
