= RS
mmmh??
To transform one side of the equation into the other using trigonometric identities, we can start with the left side of the equation, cos Q sec Q, and try to simplify it to match the right side, which is 1.
First, let's recall some trigonometric identities:
1. The reciprocal identity: sec Q = 1/cos Q
Using this identity, we can rewrite the left side of the equation as:
cos Q sec Q = cos Q * (1/cos Q)
Next, we can simplify by canceling out the cosine terms:
cos Q * (1/cos Q) = 1
Now, we have simplified the left side of the equation to match the right side, which is 1. Therefore, using the trigonometric identity of the reciprocal, we have successfully transformed one side of the equation into the other.
