Question

1. Prove the following identities:
a. (1 - cos? @)sec0 = tan? O
b. sin 0(1+tan 0) + cos (1 + cot 8) = sec + cosec
c. sin cot + sin @ cosec @ = 1 + cos 0
d. sec A(1 - sin A)(sec A + tan A) = 1
sec 0(1 + sin )(sec 0 - tan 8) = 1
f. cosec O(1 + cos O)(cosec 0-cot 0) = 1
1+ sin A _cosecA +1
g
1-sin A cosecA-1
e.
