∫secxsecx+tanxdx=
tanx-secx+c
log1+secx+c
secx+tanx+c
logsinx+logcosx+c
Explanation for correct option:
Evaluate ∫secxsecx+tanxdx
consider the given equation as
I=∫secxsecx+tanxdx
Multiply and divided by secx-tanx in the above Equation
I=∫secxsecx-tanxsecx+tanxsecx-tanxdx⇒I=∫sec2x-secx.tanxsec2x-tan2xdx⇒I=∫sec2x-secx.tanxdx⇒I=tanx-secx+c
Hence, the correct answer is Option A.
