How does that end up????

- Trig -
**Reiny**, Thursday, December 22, 2011 at 11:21pmNotice there are only 3 trig names

all have matching co-function

sine --- cosine

secan ---cosecant

tangent -- cotangent , so that

sinØ = cos(90°- Ø)

secØ = csc(90° - Ø)

tanØ = cot(90° - Ø)

so tan 88° = cot 2°
