Question 1203876: Please help me with my homework!!!!!

Use trigonometric identities to transform the left side of the equation into the right side (0 < ๐›ผ < ๐œ‹/2).
tan ๐›ผ cos ๐›ผ = sin ๐›ผ
tan ๐›ผ cos ๐›ผ =
sin ๐›ผ


ยท cos ๐›ผ
= sin ๐›ผ

next time don't copy and past, it is very hard to read what question is

Use trigonometric identities to transform the left side of the equation into the right side
(0+%3C+theta+%3C+pi%2F2)
proof that left side is equal to right side

tan%28theta%29%2A+cos%28theta%29++=+sin%28theta%29+

Use trigonometric identity: tan+%28theta%29+=sin%28theta%29+%2Fcos%28theta%29

%28sin%28theta%29+%2Fcos%28theta%29%29%2Acos+%28theta%29++=+sin%28theta%29+



sin%28theta%29++=+sin%28theta%29+



Use trigonometric identities to transform the left side of the equation into the right side
(0+%3C+theta+%3C+pi%2F2)
.
cot%28theta%29+sin%28theta%29+=cos%28theta%29
Use trigonometric identity: cot%28theta%29+=+cos+%28theta%29%2Fsin%28theta%29
%28cos+%28theta%29%2Fsin%28theta%29%29sin%28theta%29+=cos+%28theta%29
%28cos+%28theta%29%2Fcross%28sin%28theta%29%29%29cross%28sin%28theta%29+%29=cos+%28theta%29
cos+%28theta%29=cos+%28theta%29


Use trigonometric identities to transform the left side of the equation into the right side (0+%3C+theta+%3C+pi%2F2)


%281+%2B+cos+%28theta%29%29%28+1+-+cos+%28theta%29+%29=sin%5E2%28theta%29
1+-+cos%5E2+%28theta%29+=sin%5E2%28theta%29........use identity sin%5E2%28theta%29%2Bcos%5E2+%28theta%29+=1, then sin%5E2%28theta%29=1+-+cos%5E2+%28theta%29+
sin%5E2%28theta%29=sin%5E2%28theta%29



Use trigonometric identities to transform the left side of the equation into the right side (0+%3C+theta+%3C+pi%2F2)

sin%5E2%28theta%29-cos%5E2+%28theta%29=2sin%5E2%28theta%29-1.....use identity sin%5E2%28theta%29%2Bcos%5E2+%28theta%29+=1, then cos%5E2%28theta%29=1+-+sin%5E2+%28theta%29+
sin%5E2%28theta%29-%281+-+sin%5E2+%28theta%29+%29=2sin%5E2%28theta%29-1
sin%5E2%28theta%29-1+%2B+sin%5E2+%28theta%29+%29=2sin%5E2%28theta%29-1
2sin%5E2%28theta%29-1=2sin%5E2%28theta%29-1


Use trigonometric identities to transform the left side of the equation into the right side (0+%3C+theta+%3C+pi%2F2)



use identities: sin%28theta%29=1%2Fcsc%28theta%29 and cos%28theta%29=1%2Fsec%28theta%29







use identity sec%5E2%28theta%29%2Bcsc%5E2%28theta%29=csc%5E2%28theta%29+sec%5E2%28theta%29

...simplify

csc%28theta%29+%2Asec+%28theta%29=csc%28theta%29+%2A+sec+%28theta%29
