I can't seem to find the right answer for this integral:

or

∫ (11*sinx + 14*tanx)dx

it would be awesome if you could show the steps too. thanks!!

Re: indefinite integral problem
$\int \sin x ~dx = -\cos x +C$ and $\int \tan x ~dx = -\ln (\cos x) +C$

so...

Hi,
first u split the given integral function i.e 11∫sinx dx+14∫tanx dx then u integrate, u got the result i.e -11cosx+14log(secx)+c
