What to Focus On
- sin θ = opposite / hypotenuse
- cos θ = adjacent / hypotenuse
- tan θ = opposite / adjacent
- cosec θ = 1 / sin θ
- sec θ = 1 / cos θ
- cot θ = 1 / tan θ = cos θ / sin θ
- sin θ × cosec θ = 1
- cos θ × sec θ = 1
- tan θ × cot θ = 1
Common Mistakes to Avoid
cosecθ is the reciprocal of cosine.
secθ is the reciprocal of sine.
cotθ is the reciprocal of cosine.
Memory Tips
sin, cos, tan from a right triangle
cosec, sec, cot as reciprocals
Which ratio belongs to which side form
cosec theta = AC/AB in the triangle
