Question

(D) આપેલ છે કે,$f\left(\frac{t+1}{2 t+1}\right)=t+1$. ધારો કે $\frac{t+1}{2 t+1}=x$. તેથી $t+1=x(2t+1) \Rightarrow t+1=2tx+x$. $t(1-2x)=x-1 \Rightarro

Vedclass · Accepted Answer

$\frac{x}{2}+\frac{1}{4} \log (2 x-1)+c$

Vedclass · Answer

(D) આપેલ છે કે,$f\left(\frac{t+1}{2 t+1}\right)=t+1$. ધારો કે $\frac{t+1}{2 t+1}=x$. તેથી $t+1=x(2t+1) \Rightarrow t+1=2tx+x$. $t(1-2x)=x-1 \Rightarrow t=\frac{x-1}{1-2x}=\frac{1-x}{2x-1}$. $f(x)$ ના પદમાં $t$ ની કિંમત મૂકતા: $f(x) = \frac{1-x}{2x-1} + 1 = \frac{1-x+2x-1}{2x-1} = \frac{x}{2x-1}$. હવે,સંકલન મેળવીએ: $\int f(x) dx = \int \frac{x}{2x-1} dx = \frac{1}{2} \int \frac{2x}{2x-1} dx$. $= \frac{1}{2} \int \frac{2x-1+1}{2x-1} dx = \frac{1}{2} \int \left(1 + \frac{1}{2x-1}\right) dx$. $= \frac{1}{2} \left[ x + \frac{1}{2} \log |2x-1| \right] + c$. $= \frac{x}{2} + \frac{1}{4} \log |2x-1| + c$.

જો $f\left(\frac{t+1}{2 t+1}\right)=t+1$ હોય,તો $\int f(x) d x=$
