Question

If sin = cos then find tan .​

Answer 1

sin ∅ = cos ∅

sin ∅ / cos ∅ = 1.

•tan ∅ = 1• [ sin ∅/cos ∅ = tan ∅ ]•

•tan ∅ = tan 45° •( tan 45° = 1 )•

• => ∅ = 45° <= •

hope it helps you

Answer 2

$sin \: ∅ = cos \: ∅$

$\frac{sin∅}{cos∅} = 1$

$tan∅ = 1( \frac{sin∅}{cos∅} = tan∅)$

$tan∅ = tan45° \: (tan45° = 1)$

$=>∅ = 45°<=$
