Verify the identity COS X + cos x tan?x sec x To verify the identity, start with the more complicated side and transform it to look like the other side. Choose the correct transformations and transform the expression at each step COS X + cos x tan = cos() (Do not simplify.) Apply a reciprocal identity Separate the quotient into two terms Apply the appropriate even - odd identity (Do not simplify) Factor out the greatest common factor, cos x...
