sin (90 - θ) = cos θ

cos(90 - θ) = sin θ

tan(90 - θ) = cot θ

cot(90 - θ) = tan θ

sec(90 - θ) = cosec θ

cosec(90 - θ) = sec θ

sin (90 + θ) = cos θ

cos(90 + θ) = -sin θ

tan(90 + θ) = -cot θ

cot(90 + θ) = -tan θ

sec(90 + θ) = -cosec θ

cosec(90 + θ) = sec θ

sin(180 - θ) = sin θ

cos(180 - θ) = -cos θ

tan(180 - θ) = -tan θ

cot(180 - θ) = -cot θ

cosec(180 - θ) = cosec θ

sec(180 - θ) = -sec θ

sin(270 - θ) = -cos θ

cos(270 - θ) = -sin θ

tan(270 - θ) = cot θ

cot(270 - θ) = tan θ

sec(270 - θ) = -cosec θ

cosec(270 - θ) = -sec θ

sin(360 - θ) = -cos θ

cos(360 - θ) = sin θ

tan(360 - θ) = -cot θ

cot(360 - θ) = -tan θ

sec(360 - θ) = cosec θ

cosec(360 - θ) = -sec θ

tan θ = sin θ / cos θ

sin θ = 1/cosec θ

cos θ = 1/sec θ

cot θ = cos θ / sin θ

sin² θ + cos² θ = 1

1 + cot² θ = cosec² θ

1 + tan² θ = sec² θ
