Question

Match each ratio in the first row with an equivalent ratio from the second row if angle A plus angle B = 90 degrees.
SinA CosA TanA CscA SecA CotA
SinB CosB TanB CscB SecB CotB
Pleaseeee help!!

Answer 1

f(a) = co-f(b) if a+b = 90
that is, <b>co</b>sine(a) = sin(b) if a is <b>co</b>mplementary to b

So,
sinA = cosB
tanA = cotB
secA = cscB
etc.
