(\partial)/(\partial x)(sin^2(ax))

\frac{\partial}{\partial x} (sin^{2} (a x))

a sin (2 a x)

Solution steps

\frac{\partial}{\partial x} (sin^{2} (a x))

Apply the chain rule:

2 sin (a x) \frac{\partial}{\partial x} (sin (a x))

= 2 sin (a x) \frac{\partial}{\partial x} (sin (a x))

\frac{\partial}{\partial x} (sin (a x)) = cos (a x) a

= 2 sin (a x) cos (a x) a

Use the Double Angle identity:

2 sin (x) cos (x) = sin (2 x)

= a sin (2 a x)

\frac{\partial}{\partial y} (\frac{1}{x} + \frac{1}{y})

\int 5 e^{5 x} sin (e^{5 x}) d x

\int 2 cos (x) d x

x \to 5 lim (cos (\frac{1}{x - 5}))

y = x^{2} - 2 x + 3, x = - 2, x = 1
