Question

If sec theta minus tan theta is equal to P then find the cos theta

Answer 1

Answer:

Step-by-step explanation:sec theta-tan theta=p

1/cos theta-sin/cos=p

1-sin/cos=p

Cos theta=p(1-sin)

Answer 2

Answer:

hi.

Step-by-step explanation:

sec∅ - tan∅=p                                 .( 1 )

now , w k t ,

sec²∅ - tan²∅=1

(sec∅ - tan∅)(sec∅ + tan∅) = 1  , (using a²-b²=1)

p(sec∅ + tan∅) = 1

(sec∅ + tan∅) = 1/p                                 (2)

adding 1 and 2

2sec∅= p+1/p

2sec∅= (p²+1)/p

sec∅=  (p²+1)/2p

cos∅= 2p/ (p²+1)
