It is mathematically written as "atan x" (or) "tan-1 x" or "arctan x". We read "tan-1 x" as "tan inverse x". If two functions f and f-1 are inverses of each other, then whenever f(x) = y , we have x …
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: WebWhat is the formula for tan 3 x?
