Question

If tan theta =1, then find the values of sin theta + cos theta/ sec theta + cosec theta

Answer 1

Answer:1/2

Let thetha be x

now,

tan x = 1 (given )

or , sin x/cos x = 1

or , sin x = cos x

so, x = 45 Degree

=sin x + cos x / sex x + cosec x

=(sin x + cos x ) / (1/cos x + 1/ sin x )

=( ( sin x + cos x ) / (sin x + cos x ) ) .sin x .cos x

=sin x .cos x

= sin 45 .cos 45 ( x = 45 )

=1/2
