From
(sec a - cos a) / tan a = sin a
Convert the left side to all sines and cosines...
((1/cos a) - cos a) / (sin a / cos a) =
Now multiply it by cos a / cos a and get
(1 - cos^2 a) / sin a =
sin^2 a / sin a =
sin a = sin a
and we're done.

Sec a- Cos a/ Tan a = Sin a..I THINK IT SHOULD BE COSEC(A)AND NOT SEC(A)
COSEC(A)-COS(A)/TAN(A)
LHS=1/SIN(A)-COS(A)*COS(A)/SIN(A)={1-COS^2(A)}/SIN(A)=SIN^2(A)/SIN(A)=SIN(A)=RHS
