capital A number three. And then we need to integrate cost two X cost four X and cost six because two weeks into cause four X into cost six X. Dx. So we have to integrate it. No Okay so let us first take this and I legislated A so we'll be first writing course two works cause for X as one by two of course A plus B. That is cause two X plus four X six X plus pass A minus B. Which will be A cause two x minus four X minus two X one by two cause six X. Bless cost to it and so on. Let us plug in here I will be able to one by two cause six X. MS cause two X into because six X. Dx. So this will become one by two causes choir six set the X less course two weeks plastic sex dx. Okay here from double angle formula in trigonometry we can write it as this is going to spread. Uh of course to theater is two courses quietly done minus one. So we will be having uh this as cause one place cause to theater that is 12 X by two D X plus here again as we have been told earlier will be equal to only just write one by two over here also mm one by two and again one by two. And it will be cause two plus 68 X cause a tex less cost four X. Dx. Okay, so this will be won by four and integration of one by two. Integration of one by two will be equal to one by two X. Bless integration of Okay no problem. Will be just uh doing life one before will be taken outside and we'll be doing integration of one. It will be X plus indication of cost 12 rex is saying well that's by well less This is one by four Integration of course a tax of course a taxes 98 X by eight plus cost four X is saying four X by four. Let's see. Okay, so one by four will be taken as common and we'll be writing this is signed 12 back so one by 12 sign 12 X. Well, bags plus this X bless one by eight, saying eight X less one by four Science Fedex. So they should be dancing. Thank you so much.
