Question

The equations frwdx = Jut()dy and fr"W8x=*#*?W-S4 & F"() dx, where y = r "(a) for the first formula and tº 1 is integrable, give the two different formulas for the integral of cos shown below Can both integrations be correct? Explain ſcos * 'xdx => 'x-sin (cos') + c ſcos 'xdx = xcos IX-V7-x+C = Xcos Choose the correct answer below. OA. No, because cos'x is not integrable. ОВ. Yes, because /1 - (cos is equal to cos OC. Yes, because both formulas are valid and cos 'x is integrable. OD No, because sin (cos'x) is not equal to 1-x?

Answer 1

Option A is correct answer because you can't integrate cos-1x

so, option A is correct answer
