To find the integral of x2 dy + 2xy dx
If space we space take space derivative space of space straight x squared straight y space straight i. straight e. space straight d over dx open parentheses straight x squared straight y close parentheses space then space we space get straight d over dx open parentheses straight x squared straight y close parentheses equals straight x squared dy over dx plus 2 xy straight d open parentheses straight x squared straight y close parentheses equals straight x squared dy plus 2 xy space dx Therefore comma space integral straight x squared dy plus 2 xy space dx equals integral straight d open parentheses straight x squared dy plus 2 xy space dx close parentheses space equals space straight x squared straight y plus straight C

Sir please tell me how to integrate sin inverse x wrt x . Please use the formula which integrates product of 2 functions in that formula i took 1 as g(x) and sin inverse x as f(x) I obtained by the formula x.sininverse x - integral of x/(1-x^2)^1/2 DX I substituted x^2 as t but in my final answer there was negative sign after x.sin inverse x which should be + as per the correct answer please resolve my doubt .
