Here "ln" stands for natural logarithm and 'C' is the integration constant. Explanation: You can also see this this way: ∫sec2xtanxdx = ∫secx(secxtanx)dx. In the next example, we see the strategy that must be applied when there are only even powers of sinx and cosx.. It is written in mathematical form as follows. ∫secxtanxdx = secx + C. Exercise 7. The function F (x) F ( x) can be found by finding the indefinite integral of the derivative f (x) f ( x). \int sec^{2}\left(x\right) pt. But the more popular formula is, ∫ sec x dx = ln |sec x + tan x| + C. We have multiple formulas for this. In 1599, Edward Wright evaluated the integral by numerical methods – what today we would call Riemann sums. And after integration by parts with differentiating 1 − sinx and integrating − sinx cos2x I obtain erroneously. For the given integral intxsec^2(x)dx, we want to choose a value of u that gets simpler when we differentiate it and a value of dv that is easily integrated. Evaluate ∫cos3xsin2xdx.

This did not seem to be close to tanx, and sure enough the result came out to be 1 sin ( x) cos ( x) − csc(x) + ln|tan(x) + sec(x)| + C. The integral of the secant function was one of the "outstanding open problems of the mid-seventeenth century", solved in 1668 by James Gregory. tanx +C d/dx (tanx) =sec^2x, so tanx in an antiderivative of sec^2x and the general antiderivative of sec^2x is tanx+C.2. This is equivalent to the other answer of tan2x 2 +C because tan2x and sec2x are only a constant away from one another through the equality tan2x + 1 = sec2x. 1 sinxcosx + ∫ 1 sin2xcosx. ∫ sec 2 x d x = tan x + C. cos2x = 1 2 + 1 2cos(2x) = 1 + cos(2x) 2. 0.
