Transcribed Image Text:NOTE: You can save memorizing tangent identities by simply treating tangent as sine/cosine !
sin(A + B)=sin Acos B+cos Asin B
cos(A + B) = cos A cos B-sin Asin B
sin(A-B)=sin Acos B-cos Asin B
cos(4-B) = cos AcosB + sin Asin B
sin(A + B)
tan(A + B)=
tan(4-B)=
sin(A - B)
cos(A - B)
cos(A + B)
