Question

prove that (sec +tan)(1-sin)=cos​

Answer 1

Answer:

(sec + tan )(1-sin)

(1/cos+sin/cos)(1-sin)

((1+sin)/cos)(1-sin)

(1-sin^2)/cos

cos^2/cos

cos

Answer 2

Answer:

Step-by-step explanation:

LHS

(1/cos + sin/cos)(1-sin)

((1+sin)/cos)(1-sin)

cos*cos/cos    (1-sin*sin=cos*cos)

cos=Rhs
