Final answer:
The simplified form of the expression cot B tan ß, using fundamental trigonometric identities, is simply 1, since cot B is the reciprocal of tan B.
Step-by-step explanation:
The question relates to the use of fundamental trigonometric identities to simplify the expression cot B tan ß. We know that cot B is equal to 1/tan B, therefore when it is multiplied by tan ß, we can use the identity tan B = 1/cot B to show that cot B tan ß simplifies to 1/tan B * tan B, which simplifies further to 1. As a result, the simplified form of the expression cot B tan ß is 1, regardless of the value of ß, so long as tan B is not equal to zero.
