Question

Write all the other trigonometric ratios of ∠A in terms of sec A.​

Answer 1

Answer:

We know, 

cosA=secA1

We know, 

sin2A+cos2A=1

sin2A=1−cos2A

sinA=1−(secA1)2=sec2Asec2A−1=secAsec2A−1

∴sinA=secAsec2A−1

We know, 

cosec A=sinA1

∴cosec A=sec2A−1secA

We know, 

cotA=sinAcosA==secA
