y=ex y=e^{x} y=ex হলে, y4 \mathrm{y}_{4} y4 কত ?
e^x কে differentiate করলে e^x ই থাকে
f(x)=lnx,g(x)=(x+1+x2)f(x)=\ln x, g(x)=\left(x+\sqrt{1+x^{2}}\right)f(x)=lnx,g(x)=(x+1+x2)
y=lnex2 y=\operatorname{ln} e^{x^{2}} y=lnex2 হলে y2=? y_{2}=? y2=?
দৃশ্যকল্প: f(x,y)=x+y−2,t=2sin−1x\mathrm{ f(x, y)=\sqrt{x}+\sqrt{y}-\sqrt{2}}, \mathrm{t=2 \sin ^{-1} x} f(x,y)=x+y−2,t=2sin−1x.
দৃশ্যকল্প: g(x)=xcosec−11x,y=cos(msin−1p) \mathrm{g}(\mathrm{x})=\mathrm{xcosec}^{-1} \frac{1}{\mathrm{x}}, \mathrm{y}=\cos \left(\mathrm{msin}^{-1} \mathrm{p}\right) g(x)=xcosec−1x1,y=cos(msin−1p)
