Solution a. \(sin 5π/8←cos⁡(π/2+5π/8)=cos (4π-5π)/8=(-π)/8 \) b. \(cot 9π/10←Tan⁡(π/2+9π/10)=cos (5π-9π)/10 \)= c. \(sec146°(42)^'=csc⁡( 90°-146°(42)^' \))= d. \(Tan174°(03)^'=c⁡ot( 90°-174°(03)^' \))= e. \( Cot 176.9814°=Tan⁡〖 ( 90°-176.9814° \))= Solution a./(=cos (4π-5π)/8=(-π)/8=22.5 /) b. /(=cos (5π-9π)/10=(-4π)/10=72/) c. /(sec146° 42^'=csc⁡( 90°-146° 42^' )=-56.7 /) d /(. Tan174° 03^'=c⁡ot( 90°-174° 03^' )=-84.05. /) e. /( Cot 176.9814°= Tan⁡( 90°-176.9 /)
