Question

iii) Complete the following

sin ratio =
cos ratio = tan ratio =​

Answer 1

Step-by-step explanation:

sinθ=opposite hypotenuse,

cosθ=adjacent hypotenuse,

tanθ=opposite adjacent.

Allied to these are the three reciprocal ratios, cosecant, secant and cotangent: cosecθ=

,secθ=hypotenuse adjacent

,cotθ=adjacent opposite.

cosecθ=1sinθ,secθ=1cosθ,cotθ=1tanθ.

Answer 2

• sin ratio = opposite hypotenuse.
• cos ratio = adjacent hypotenuse.
