ddxtan−1(1−x1+x)=\displaystyle\frac{d}{dx}\tan^{-1}\left(\displaystyle\frac{1-x}{1+x}\right)=dxdtan−1(1+x1−x)= ____________.
21+x2\displaystyle\frac{2}{1+x^2}1+x22
−11+x2\displaystyle\frac{-1}{1+x^2}1+x2−1
11+x2\displaystyle\frac{1}{1+x^2}1+x21
−21+x2\displaystyle\frac{-2}{1+x^2}1+x2−2
If u=f(x2),v=g(x3),f(x)=sinx,g1(x)=cosxu=f(x^{2}), v=g(x^{3}),f(x)=\sin x, g^{1}(x)=\cos xu=f(x2),v=g(x3),f(x)=sinx,g1(x)=cosx then find dudv\frac{du}{dv}dvdu
Let the function y=f(x)y=f(x)y=f(x) be given by x=t5−5t3−20t+7x=t^{5}-5t^{3}-20t+7x=t5−5t3−20t+7 and y=4t3−3t2−18t+3y=4t^{3}-3t^{2}-18t+3y=4t3−3t2−18t+3, where tϵ(−2,2)t\epsilon \left ( -2, 2 \right )tϵ(−2,2). Then f′(x)f^{'}(x)f′(x) at t=1t=1t=1 is ?
x=a(θ-sinθ), y=a(1-cosθ) হলে -
নিচের কোনটি সঠিক?
y=sin−1[4x1+4x] y = \sin^{- 1}{\left [ \frac{4 \sqrt{x}}{1 + 4 x} \right ]} y=sin−1[1+4x4x] হলে, (dydx)((4,2) \left ( \frac{dy}{dx} \right )_{\left ( \left ( 4 , 2 \right ) \right.} (dxdy)((4,2) এর মান কত?
