Question

evaluate the expression
1/ sec theta - tan theta

Answer 1

Let sec@= 5/4
sec@ =5/4 

As we know ,
sec@ =h/b =5/4 
p=√(5^2-4^2)=3 

now, tan@ =p/b =3/4 

so, (1 - tan@)/(1 +tan@)
=>(1 -3/4)/(1+3/4)

=>(1/4)/(7/4)=1/7 (answer)

Answer 2

1/sec x =cosx
tanx=din/cosx
cosx - sinx/cosx
taking LCM
cos^2x - sinx/cosx
cosx-sinx. is the answer
