Check whether the function f(x) = x² |x| is differentiable at x = 0 or not.
If y = √(tan √x), prove that √x (dy/dx) = (1 + y⁴)/(4y).
The derivative of tan⁻¹(x²) w.r.t. x is :
If f(x) = |tan 2x|, then find the value of f′(x) at x = π/3.
If y = cosec(cot⁻¹ x), then prove that √(1 + x²) dy/dx – x = 0.
If x = e^(cos 3t) and y = e^(sin 3t), prove that dy/dx = – (y log x)/(x log y).
