Answer:

Step-by-step explanation:

or, n=sinacosb/cosasinb

Vol 97

or, n=m (cosb/cosa)

--(2)

or, ncosa=mcosb

or, n²cos²a=m²cos²b

or, n²cos²a=m²(1-sin²b) [::, sin²a+cos²a=1]

or, n²cos²a=m²(1-sin²a/m²) [using (1)]

or, n²cos²a=m²((m²-sin²a)/m²)

or, n²cos²a-m²-sin²a

or, n²cos²a=m²-(1-cos²a)

or, n²cos²a=m²-1+cos²a

or, n²cos²a-cos²a=m²-1
