simplify y/(2sec(x+pi/2))

simplify

\frac{y}{2 sec ( x + \frac{π}{2} )}

- \frac{y sin ( x )}{2}

Solution steps

\frac{y}{2 sec ( x + \frac{π}{2} )}

Rewrite using trig identities

= \frac{y}{2 ( - \frac{1}{s i n ( x )} )}

Simplify

\frac{y}{2 ( - \frac{1}{s i n ( x )} )} : - \frac{y sin ( x )}{2}

= - \frac{y sin ( x )}{2}

28 sin (150 π t + 0.1)

- sin (- t)

sin (a - \frac{π}{3})

cos (- \frac{π}{2} - θ)

cos^{2} (π x) - sin^{2} (π x)
