simplify sin(arccos(x/a))

simplify

sin (arccos (\frac{x}{a}))

\frac{a ^{2} - x ^{2}}{a}

Solution steps

sin (arccos (\frac{x}{a}))

Use the following identity:

sin (arccos (x)) = 1 - x^{2}

= 1 - (\frac{x}{a})^{2}

Simplify

= \frac{a ^{2} - x ^{2}}{a}

cos (- \frac{π}{2} + 4 h)

\frac{1}{cos ^{3} ( x )} d x

sin^{2} (- sin^{2} (x))

cos (18 0^{\circ} - α)

2 csc (2 x - \frac{π}{4}) - 1
