Tanx-tany formula
WebWhat follows is one way to proceed, assuming you take log to refer to the natural logarithm. Recall that ∫ log(u) du = ulog(u) - u + C, where C is any real number. Using the substitution u = x + 1, du = dx, we may write ∫ log(x + 1) dx = ∫ log(u) du = ulog(u) - u + C.Now we may substitute u = x + 1 back into the last expression to arrive at the answer: WebFind the solution of \cos {x} = \frac {1} {2} . Solution: We know that \cos {\frac {π} {3}} = \frac {1} {2} . Therefore, \cos {x} = \cos {\frac {π} {3}} Using Theorem 2, we get x = 2nπ ± \frac {π} {3} Example 5 Find the solution of …
