(Section 2.8: Continuity) 2.8.13 Continuity of Composite Functions If g is continuous at a , and f is continuous at ga () , then f ± g is continuous at a . (See Footnote 6.) Continuity of Basic Trig Functions The six basic trig functions (sine, cosine, tangent, cosecant, secant, and cotangent) are continuous on their domains. More precisely, the continuity interval(s) for a basic trig function correspond(s) to its domain. Such intervals are all open. Example 12 Assuming hx = sec 1 x ± ² ³ ´ µ
