Practice problem
Find the derivative of f(x)=cosh−1(2x2)f(x)=\cosh^{-1}(2x^2)f(x)=cosh−1(2x2)
f′(x)=4x4x2−1f'(x)=\frac{4x}{\sqrt{4x^2-1}}f′(x)=4x2−14x
f′(x)=2x1−4x2f'(x)=\frac{2}{x\sqrt{1-4x^2}}f′(x)=x1−4x22
f′(x)=14x2−1f'(x)=\frac{1}{\sqrt{4x^2-1}}f′(x)=4x2−11
f′(x)=4xsinh(2x2)f'(x)=4x\sinh(2x^2)f′(x)=4xsinh(2x2)
Type a concept, like “slope” or “photosynthesis”.
