Evaluate the following integrals :\(\int\)\(\frac{1+cotx}{x+log\,sinx}\)dx |
|
Answer» Assume, x + log(sinx) = t d(x + log(sinx)) = dt 1 + \(\frac{cos\,x}{sin\,x}\)dx = dt (1 + cot)dx = dt Put t and dt in given equation we get, ⇒∫\(\frac{dt}{t}\) = In|t| + c But, t = x + log(sinx) = ln| x + log(sinx) | + c. |
