(a) tan(x) = sin(x) cos(x) 1 sec(x) = - sin2(x) O sec(x) tan(x) = = sin(x) Cos(x) O cos(x) sin(x) = tan(x) - 1
(a) tan(x) = sin(x) cos(x) 1 sec(x) = - sin2(x) O sec(x) tan(x) = = sin(x) Cos(x) O cos(x) sin(x) = tan(x) - 1 = sec(x) cos(x) sec(x) tan(x)= = sin(x) O cos(x) sin(x) = cot(x) - 1 CSC(x) O sec(x) = - 1 Cos(x) 1 (b) sec(x) = cos(x) sec2(x) = 1 sin2(x) Osec(x) tan(x) = O cos(x) sin(x) = sec(x) tan(x) = O cos(x) sin(x) cot(x) - 1 = sin(x) Cos(x) tan(x) - 1 sec(x) cos(x) sin(x)
