Answer 2

Answer:

Hope it helps!! Mark this answer as brainliest if u found it useful and follow me for quick and accurate answers...

Step-by-step explanation:

cos a =  √1-sin2a

sec a = 1/cosa = 1/ √1-sin2a  

tan a = sina/cosa = sina/ √1-sin2a  

cosec a = 1/sina

cot a = cosa / sina =  √1-sin2a / sina
