Verify that the equation is an identity. sin x cOS X secx + = sec?x-tan? CSC X Both sides of this identity look similarly complex. To verify the identity, start with the left side and simplify it. Then work with the right side and try to simplify it to the same result. Choose the correct transformations and transform the expression at each step COS X sin x secx CSC X The left-hand side is simplified enough now, so start working...

verify algebraically cos(-x) -= sec x + tan x 1+ sin(-x) tan x + cotx=sec X CSC X
Use identities to simplify the expression. csc^x- cotx scʻx-cot *x = 1 (Simplify your answer.)
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...
