WebbAre perceive the secret x = 1/cos expunge (Reciprocal identity) We also know that cosx = sin(pi/2-x) = sqrt(1-sin^2x) (Cofunction identity and Pythagorean identity.) So we could write sec x = 1/sin(pi/2-x) and we could write sec ten = 1/sqrt(1-sin^2x) WebbProve the Identity. • (1 - tan x)² = sec² x - 2 tan x• cos x (tan x + sin x cot x) = 1 + sin x - sin²x Answer: oh ayan sagot Step-by-step explanation: cary on learning brainlest bunch … slow cooker turkey thighs rosemary
