Fundamental Trig Identities Date Period Use identities to find the value of each expression. 1) If sin 0 = -0.93, find cos (0 - ) 2) If tan (-0) =-1.48, find cot ( - ). 3) If cos (0 - - =-0.52, find sin 0. 4) If sin 0 = 0.16, find cos ( - e) 5) If sec 0 =4.45, find csc (5 -0) 6) If sin (0 - = =-0.22, find cos (-0). 7) If tan 0 =-0.87, find cot ( -) 8) If csc ( - 0) =-1.11, find sec (-0). 9) Find sin O and sec 0 10) Find csc 0 and sin 0 if tan 0 = 3 and cos 0 and sin 0 0. 13) Find cot O and cos 0 14) Find cos O and sec 0 if csc 0 = - and cos 0 0. -1- Verify each identity. 17) sin xsec x = tan x 18) sin xcot x cos x 19) sec x - csc x = tan x - cot? x 20) esc' xcos x = csc' x - 1
