Answer 1

Answer:

you have already written the answer

Answer 2

Answer:

sine and cosine negativam aur positivam bam answer sameang askang teachearanghscholam

Step-by-step explanation:

use calculation

sinA+cosA=1

or sinA=1-cosA

by substitution method in eqn. 2,

1-cosA-cosA=1

or 1-cosA=1+cosA

Hence, proved
