Question

prove that cos theta minus sin theta upon cos theta is equal to 1 minus 10 theta​

Answer 1

cos theeta - sin theeta /cos theeta = 1 - tan theeta

by taking RHS

1 - tan theeta

= 1 -. sin theeta / cos theeta

= cos theeta - sin theeta / cos theeta

= LHS

Answer 2

Answer:

so easy

Step-by-step explanation:

put denominator each numerator

cos theta/cos theta =1

sin theta/cos theta = tan theta
