Integration of Circular Functions (VCE SSCE Mathematical Methods): Quizzes

$-\frac{1}{k} \cos(kx + a) + c$

$\frac{1}{k} \sin(kx + a) + c$

Frequency

Phase shift (horizontal translation)

$-\frac{1}{3} \cos(3x + \frac{\pi}{4}) + c$

$-\frac{1}{16} \cos(4x) + c$

$\frac{1}{2}$

$4$ square units

Because of the chain rule working in reverse

Take the negative of the integral
