Then prove your Donjecture. csc x+ cot x Conjecture what the nght side ofthe identity should be. inemmediate step to prove the corjecture? which of the lolowing serves as an 2 cotx 2csc x cack to select your answerts) 7.1

Solution

1/(cscx + cotx) + 1/(cscx - cotx)

= ( cscx - cotx + cscx +cotx)/(csc^2x - cot^2x)

= 2cscx/(csc^2x - cot^2x)

Option C
