Question

Evaluate : (sec² theeta - 1) ( cosec ² theeta - 1)​

Answer 1

Answer:

Step-by-step explanation:

(sec²Ø-1) (cosec ² -1)

We have ,

sec²ø - tan² ø= 1

Cosec² ø- cot²ø = 1

So,

(Sec²ø-1)(cosec²ø-1) = tan²ø.cot²ø

=> tan²ø . 1/tan²ø ( since , cot A = I/tanA)

Cancel tan²ø on both sides

=> 1

Answer 2

Step-by-step explanation:

(1/cos )square theta-1)(1/sin thita square)
