join arccos(x)+arcsin(2x)-pi/2

join

arccos (x) + arcsin (2 x) - \frac{π}{2}

\frac{2 arccos ( x ) + 2 arcsin ( 2 x ) - π}{2}

Solution steps

arccos (x) + arcsin (2 x) - \frac{π}{2}

Convert element to fraction:

arccos (x) = \frac{arccos ( x ) 2}{2}, arcsin (2 x) = \frac{arcsin ( 2 x ) 2}{2}

= \frac{arccos ( x ) \cdot 2}{2} + \frac{arcsin ( 2 x ) \cdot 2}{2} - \frac{π}{2}

Since the denominators are equal, combine the fractions:

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

= \frac{arccos ( x ) \cdot 2 + arcsin ( 2 x ) \cdot 2 - π}{2}

y = - 16 x^{2} + 121 x + 83

f (x) = - 2 x^{2} + x + 1

f (H) = H^{2}

f (x) = x^{2} + 3 x
