SinA CosA TanA CscA SecA CotA

SinB CosB TanB CscB SecB CotB

Pleaseeee help!!

SinA CosA TanA CscA SecA CotA

SinB CosB TanB CscB SecB CotB

Pleaseeee help!!

## Answers

f(a) = co-f(b) if a+b = 90

that is,cosine(a) = sin(b) if a iscomplementary to b

So,

sinA = cosB

tanA = cotB

secA = cscB

etc.
