Question

Express each of the following in terms of trigonometric ratios of angle between zero to 45 degree

Answer 1

cot 49 = cot(90-41) =tan 41
cosec 87= cosec(90-3) = sec3

cot49 +cosec 87 = tan41+ sec3

Answer 2

Answer:

cot 49° = cot ( 90° - 41°) = tan 41

cosec 87° = cosec ( 90° - 3 ) = sec 3

cot 49 + cosec 87 = tan 41 + sec 3

answer= tan 41+ sec 3
