Hello friends, please solve it. It will be so helpful for me, if you solve these problems. This is trigonometric ratios problems. This is of ; Prove that :- one part :-
1. secA X cotA X cosecA = cosec^2A
2. cosA X tanA X cosecA = 1
3. sinA X cotA X secA = 1
4. cotA X secA X cosec^2A = cosec^3A
5. (1-sin^2A) + 1/cosec^2A = 1
Please solve it A.S.A.P...
*THANKYOU*

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities.
