Question

(ix)
1
(cosec A - sin A)(sec A - cos A) =
tan A + cot A
[Hint: Simplify LHS and RHS separately]​

Answer 1

Step-by-step explanation:

Unit of pressure: pascal (Pa)

Pressure is the amount of force applied perpendicular to the surface of an object per unit area and the for it is p (or P). The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m2, or kg·m−1·s−2).

Answer 2

Answer:

Mark as brainliest

LHS=(cosecA−sinA)(secA−cosA)=(sinA1−sinA)(cosA1−cosA)

                                       =(sinA1−sin2A)(cosA1−cos2A)=sinAcosA=1/2sin2A

RHS=tanA+cotA1=1+tan²A/tanA=1/2sin2A

LHS=RHS

Hence Proved
