Identify the equation as either an identity or not. 13) 1 + CSC X = COS X + cotx sec X A) Identity B) Not an identity 14) sin 0 sec 0 = cos o esco A) Not an identity B) Identity sin X_= 2 CSC X 15) + sin x 1 - COS X 1+cOS X A) Identity B) Not an identity
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
