Document Summary

Provide a generalization to each of the key terms listed in this section. Local m axima : 1 at x = Local m inima : 1 at x = . Y intercepts : n one f (x) = cot (x) What do tangent and cotangent have in common? tan(x) = cot(x) tan (x) = cot (x) tan (x) cot (x) = 0 cos (x) sin (x) cos (x) cos (x) cos (x) sin (x) sin (x) cos (x) = 0 sin (x) sin (x) cos (x) sin (x) Cos2 (x) + sin2 (x) cos (x) sin (x) Cos2 (x) + sin2 (x) = 0. Cos (2x) = 0 cos (2x) = 0. What do cosecant and secant have in common? csc(x) = sec(x) csc (x) = sec (x) csc (x) sec (x) = 0. 1 cos (x) sin (x) cos (x) sin (x) = 0 cos (x) cos (x) sin (x)
