 Hello and how are you all there my name is Priyanka and I shall be helping you with the following question It says integrate the following now the 19th function, which is given to us is Cos 2x plus 2 sine square x divided by cos square x Now let us quickly integrate this function We have cos 2x plus 2 sine square x We will divide it by cos square x with respect to dx Now here We can write cos 2x as 1 minus 2 sine square x, right? So 1 minus 2 sine square x plus 2 sine square x divided by cos square x to dx on simplifying We have further as 1 divided by cos square x into dx Which is equal to the integral of secant square x dx and that is 10x plus c So this is the required answer to the session understood it well and keep enjoying
