Consider the given equation. cos(x)sec(x) sin(x) = csc(x) ? sin(x) (a) Verify algebraically that the equation is an identity. Use a Reciprocal Identity to rewrite the expression in terms of sine and cosine only. (Simplify your answer completely.) cos(x)sec(x) sin(x) = cos2(x)sin(x)? Great work. Use a Pythagorean Identity to rewrite the expression in terms of sine only. = Use the appropriate trigonometric function(s). Simplify to confirm the given identity. cos(x)sec(x) sin(x) = sin(x)
