Question

Sebutkan minimal 5 rumus identitas trigonometri!

Trims:)

Answer 1

1. CosecP = 1/ sinP
2. secP = 1/cosP
3. cotanP = 1/ tanP
4. tanP = sinP/cosP
5. CotanP = CosP/SinP

Answer 2

Sin^2x + cos^2x = 1
tan^2x + 1 = sec^2x
sinx / cosx = tanx
1 + cot^2x = csc^2x
sin^3x + cos^3x = (sinx+cosx)^3 - 3sinxcosx . (sinx+cosx)
