simplify (dx)/(cos^2(x))

simplify

\frac{d x}{cos ^{2} ( x )}

sec^{2} (x) d x

Solution steps

\frac{d x}{cos ^{2} ( x )}

Use the basic trigonometric identity:

\frac{1}{cos ( x )} = sec (x)

= d x sec^{2} (x)

cos (y + π)

sin (n - \frac{π}{2})

cos (- π x)

cot (arccos (\frac{x}{5}))

j^{2} cos (- π t + \frac{π}{2})
