5x √x dx = soal : integral lima x akar x = tolong ya bingungg soalnya jawabannya 5/2 x² + X atau 2x²√x +C Subinterval2 : 0,5 - 1 dengan $ x_2 = 1 \rightarrow f(x_2) = f(1) = 1^2 = 1 $ ^n \frac{1}{n} \cos \pi (\frac{i}{n}) = \int \limits_a^b f(x) dx = \int \limits_0^1 \cos \pi x dx $ Jadi, bentuk integral tentunya adalah $ \int \limits_0^1 \, \cos \pi x \, dx $ . Bagaimana dengan materi Jumlah Riemann yang ada pada artikel ini? Pasti seru dan Nowwe may substitute u = x + 1 back into the last expression to arrive at the answer: ∫ log(x + 1) dx = (x + 1)log(x + 1) - x + C, where C is any real number. If you take log to mean logarithm to the base ten, you would proceed exactly as above, using the relation log(x) = ln(x) / ln(10). The answer would then be ∫ log(x + 1) dx 15 Answers to the question of the integral of 1 x 1 x are all based on an implicit assumption that the upper and lower limits of the integral are both positive real numbers. If we allow more generality, we find an interesting paradox. For instance, suppose the limits on the integral are from −A − A to +A + A where A A is a real, positive Given ∫ 1 + x 1 − x dx. We know that 1 + x 1 − x = 2 − (1 − x) 1 − x. = 2 1 − x −1. Now, we got ∫( 2 1 − x −1) dx. Using the sum rule, ∫(f (a) +f (b)) dx = ∫f (a) +∫f (b) So, we have. = ∫ 2 1 − x dx − ∫1 dx. Now, we use u-substitution to compute ∫ 2 1 −x dx. Let u = 1 − x, then du dx = − 1,dx = du Notethat tanθ = x and secθ = √1 +tan2θ = √1 +x2: I = ln∣∣x +√1 + x2∣∣ +C. Answer link. lnabs (x+sqrt (1+x^2))+C I=int1/sqrt (1+x^2)dx Let x=tantheta. This implies that dx=sec^2thetad theta. I=int1/sqrt (1+tan^2theta)sec^2thetad theta Since 1+tan^2theta=sec^2theta: I=intsecthetad theta=lnabs (sectheta+tantheta) Note that PMGbl.
