Usenow the trigonometric identity: sec2 − 1 = tan2t. and as for ∈ [0, π 2) the tangent is positive: √sec2 −1 = tant. so: ∫ √x2 −25 x dx = 5∫tan2tdt. using the same identity again: ∫ √x2 −25 x dx = 5∫(sec2t −1)dt. and for the linearity of the integral:

1 Trigonometrically: x = 2cos (theta), or 2sin (theta), not. You cant use the double angle identity without making that substitution, so its not really 'or' is it :) You might be able to do it by parts with u = sqrt (4-x^2) and dv = dx. Apr 1, 2005. #3.
Letu(x) = 1 + x2 then du(x) = 2xdx. d(u(x)) 2 = xdx. Start solving the integral. ∫ x x2 +1 dx. = ∫ d(u(x)) 2u(x) = 1 2 ∫ du(x) u(x) = 1 2 ln|u(x)| +C. = 1 2 ln∣∣x2 +1∣∣ +C. Because x2 +1 > 0 then ∣∣x2 + 1∣∣ = x2 + 1.
y= ʃ f ' (x) dx = f(x) + c Andai salah satu titik yang melalui kurva sudah diketahui, nilai c bisa diketahui sehingga persamaan kurvanya bisa ditentukan. contoh soal integral substitusi, contoh soal integral tak tentu bentuk akar, contoh soal integral tak tentu dari fungsi aljabar.
