Question

if theta =45 degree ,then find sec theeta ×cot theeta _cosec theeta ×tan theeta

Answer 1

Answer:

0

Step-by-step explanation:

sec theeta ×cot theeta - cosec theeta ×tan theeta

= (1/cos Theetha) × (cos theeta/ sin theetha)  - (1/sin theetha) × (sin theetha/cos theetha)

= (1/sin theetha )  - (1/cos theetha)

= (Cos theetha - Sin theetha)/ (sin theetha * Cos Theetha)

as theetha = 45 deg

Sin 45 = Cos 45

Cos 45 - Sin 45 = 0

Cos theetha - Sin theetha = 0

= 0 / (sin theetha * Cos Theetha)

= 0

Answer 2

so that's your answer.

as cot 45' is 1

sec 45' is root 2

cosec 45' is root 2

tan 45' is 1

so solution is these
