derivative of

cos (2 θ)

- sin (2 θ) \cdot 2

Solution steps

\frac{d}{d θ} (cos (2 θ))

Apply the chain rule:

- sin (2 θ) \frac{d}{d θ} (2 θ)

= - sin (2 θ) \frac{d}{d θ} (2 θ)

\frac{d}{d θ} (2 θ) = 2

= - sin (2 θ) \cdot 2

x \to 0 lim (\frac{8}{\frac{2 + e ^{1}}{x}})

t an g e n t f (x) = 14 x sin (x), at x = \frac{π}{2}

\int \frac{11 x ^{2}}{( 25 + x ^{2} ) ^{2}} d x

\int 30 (x + 2) (x + 3)^{4} d x

d er i v a t i v e f (x) = x^{4} - 3 x^{3} - 9 x^{2} + 5 x
