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...
Verify the identity. 1- tanx 1-tan secx Factor the numerator (tanx-1)(1+tan %) (1 - tan²x) (1-tan?:) (1+tan :) (1 - tanºx) Simplify the fraction O 1+tanºx Use an identity to simplify the expression from the previous step 1-tan O sec? 0 1
