3. Techniques of Differentiation

Find all points on the curve y = tan x, −π/2 < x < π/2, where the tangent line is parallel to the line y = 2x. Sketch the curve and tangent lines together, labeling each with its equation.

Find the derivative of the function.

Find the derivative of the function.

$f\left(x\right)=\frac{5\cos x}{2x^3}$

Find the derivative of the function.

$y=\frac{\sin \theta }{2+\cos \theta }$
